• # question_answer The electric field of a plane electromagnetic wave is given by $\vec{E}={{E}_{0}}\hat{i}\cos (kz)cos(\omega t)$ The corresponding magnetic field $\vec{B}$is then given by: [JEE Main 10-4-2019 Morning] A) $\vec{B}=\frac{{{E}_{0}}}{C}\hat{j}\sin (kz)cos(\omega t)$B) $\vec{B}=\frac{{{E}_{0}}}{C}\hat{j}\sin (kz)sin(\omega t)$C) $\vec{B}=\frac{{{E}_{0}}}{C}\hat{k}\sin (kz)cos(\omega t)$D) $\vec{B}=\frac{{{E}_{0}}}{C}\hat{j}\sin (kz)sin(\omega t)$

Correct Answer: B

Solution :

$\because$$\vec{E}\times \vec{B}||\vec{v}$ Given that wave is propagating along positive z-axis and $\vec{E}$along positive x-axis. Hence $\vec{B}$along y-axis. From Maxwell equation$\vec{\nabla }\times \vec{E}=-\frac{\partial B}{\partial t}$ i.e.$\frac{\partial E}{\partial Z}=-\frac{\partial B}{dt}$and${{B}_{0}}=\frac{{{E}_{0}}}{C}$

that doesn't make much sence.

When they open, just log in to the account that you want to enroll in to a course and click on the course name in the left column. Then enter the self-enrollment key posted in the course description.

### Foundations in Personal Finance - Dave Ramsey_2018_19

#### See payment information below.

Course Details:

Grades 9-12:  This is a challenging course and NOT recommended for middle school.  Dave Ramsey does have a middle school curriculum available, but we are using the high school level only this year.

Session Times:

Students are free to attend any class session - each week the first and second session of each section will cover the same material.

#### Class Information:

TWO OPTIONS (based on teachers volunteering)

##### OPTION 1 (full year):

Students will attend live classes two hours a week for thirty weeks (not counting breaks.)

This course is worth 1/2 credit.

Typically, it is a semester course, but we are stretching out the content to a full year.

OPTION 2 (one semester):

Students will attend live classes four hours a week for fifteen weeks (not counting breaks.)

This course is worth 1/2 credit.

So far, we have teachers willing to teach the following times.  Please understand, this is subject to change based on enrollment numbers.  If we have a large number of students enrolling, we may add sessions.  If only a few enroll, some teachers may choose to teach a different class.

Session 1:  Meets Tuesdays and Wednesdays at 9:00 AM CST (30 week course - full year - one hour class twice a week)

Session 2:  Meets Tuesdays and Thursdays @ 3:00 PM CST (30 week course - full year - one hour class twice a week)

Session 3:  Meets Mondays @ 10:00 AM to noon CST (30 week course - full year - two hour class once a week)

Live Class Option Details (Tentative - may be revised if teacher schedules require):

Mandatory Parent Meeting: TBA

Start Date:  Week of 9/10/18

Thanksgiving Break: November 10-25

Christmas Break: December 22-January 6

Easter Break:  April 13-28

Last Classes Meet: Week of 5/13/19

Description:

This course is done as a partnership with Dave Ramsey.  We will use videos and online course content from their website, and homework will be completed on Dave Ramsey's system.  Each student will be required to purchase access to Dave Ramsey's site for the video and course access.  This is equivalent to purchasing a book in a typical course.  No additional books are required beyond the online course and video access.

Students will be completing a budget, looking at their own personal finances during each chapter of this course.  There are quizzes and exams that are automatically computer-scored, as well as short essay assignments that will be scored by VHSG graders.  In addition, there are worksheets and projects assigned and started in the live class on a weekly basis.  These tasks must be checked for completion by the parent. Parents will find the assignment sheets, the worksheets and the answer keys on the VHSG Moodle site.  For this reason, a parent must be enrolled in the VHSG course for each student enrolled in order to access these materials.

Cost:

There is no charge for the VHSG portion of the course.

VHSG is charged a bulk cost for offering the class. Actual cost per student will be determined once we know how many enroll. This cost will be split evenly between students. We estimate the cost per student will be somewhere between $10 and$40 for the year course, depending how many sign up.

The cost for the online course content and videos (required to take the course) will be determined upon enrollment completion. We need to purchase our bulk teaching package from Dave Ramsey at the end of April based on enrollment numbers, so please enroll in APRIL so we order enough seats.

Seating:

Payments will need to be received by August 15 in order to finalize enrollment.

Once we have the enrollment totals at the beginning of August, we will post the amount due along with the payment instructions. Each student will need to pay by August 15 to get access to the class page.

This copy of the course is a temporary seating page for enrollment purposes only.  You will not be added to the final course page on Dave Ramsey's site until you have paid.  Information on payment will be on the temporary course page after you enroll.

End Date:  Last week of May

Description:

Age: High School (rigorous course)

36 week course, one meeting day a week

Introduction to Logic is a thorough course covering the basics of the topic. Students participating in this course should be prepared for fairly advanced thought concepts. There is a reasonable amount of reading in the text with a significant number of key terms and concepts covered. Online in-class lecture supports the text material. Students have the benefit of comprehension measurement tools (quizzes and tests). The rigorous nature of the course may suit high school students best.

Required Text:

Introductory Logic by James B. Nance and Douglas J. Wilson (4th ed.)   (May also use 5th edition)

The Fallacy Detective by Nathanial and Hans Bluedorn, 3rd ed.

### Math 3

#### Required Text:

Saxon 3, ed 1 is an exact match, other editions are fine too. On this one, go for a teacher's manual instead of the student text. There is too much the student text doesn't show and I want families to be able to track all the skills we are working on. Find it used HERE at Amazon.

#### Description:

Live online classes follow the Saxon Math 3 scope and sequence but the actual class time is filled with very game-like activities in a mix of individual and group activities. Live class activity time is followed by online practice quizzes and a weekly assessment.

#### Description:

Lessons are recorded and often interactive in format.

The online homework assignments draw questions from a large poole of question of similar type. Students get immediate feedback as they work the problem both for specific answers that they try as well as general feedback hints. The last hint points them toward ways too get live help if they need it. Finished attempts also offer the option to redo a another problem from the same question poole allowing lots of extra practice on problem types where the students feels they need extra practice. Multiple attempts are allowed but new questions are given on the new attempt instead of the same problem over and over.

Weekly tests have limited attempts to provide a true assessment of skills. If students are not satisfied with their first attempt, they may try one more time, but there will be no additional resets. The score will be an average between the two attempts. (The second test will have different questions.) Feedback is given after the test is completed.

### Saxon Algebra 1/2 - Qtr 1 - AYOP - A

NOTE:  Most students will take EITHER Saxon 87 OR Saxon Algebra 1/2, but not both.  We do not yet have Saxon 87 built for VHSG, although it is in the plans for future years.  It will not be done this year.  It depends on how many volunteers step up to help on the math upgrades when we will be able to move Saxon 87 into active development.

Saxon 87 offers more review on basic arithmetic.  If your student is still struggling with math, it may be best to use Saxon 87 to firm up the basics.  Algebra 1/2 moves faster into introductory Algebra.  Both courses are acceptable to use as a pre-algebra course prior to using Algebra.

#### Description:

Lessons are recorded and often interactive in format.

The online homework assignments draw questions from a large poole of question of similar type. Students get immediate feedback as they work the problem both for specific answers that they try as well as general feedback hints. The last hint points them toward ways too get live help if they need it. Finished attempts also offer the option to redo a another problem from the same question poole allowing lots of extra practice on problem types where the students feels they need extra practice. Multiple attempts are allowed but new questions are given on the new attempt instead of the same problem over and over.

Weekly tests have limited attempts to provide a true assessment of skills. If students are not satisfied with their first attempt, they may try one more time, but there will be no additional resets. The score will be an average between the two attempts. (The second test will have different questions.) Feedback is given after the test is completed.

Open office hours are available for students that need help. Hours are posted on the home page and students get a link on their last hint that helps them know how to get extra help when they need it.

### Saxon Algebra 1/2 - Qtr 3 - AYOP - A

NOTE:  Most students will take EITHER Saxon 87 OR Saxon Algebra 1/2, but not both.  We do not yet have Saxon 87 built for VHSG, although it is in the plans for future years.  It will not be done this year.  It depends on how many volunteers step up to help on the math upgrades when we will be able to move Saxon 87 into active development.

Saxon 87 offers more review on basic arithmetic.  If your student is still struggling with math, it may be best to use Saxon 87 to firm up the basics.  Algebra 1/2 moves faster into introductory Algebra.  Both courses are acceptable to use as a pre-algebra course prior to using Algebra.

Lessons are recorded and often interactive in format.

The online homework assignments draw questions from a large poole of question of similar type. Students get immediate feedback as they work the problem both for specific answers that they try as well as general feedback hints. The last hint points them toward ways too get live help if they need it. Finished attempts also offer the option to redo a another problem from the same question poole allowing lots of extra practice on problem types where the students feels they need extra practice. Multiple attempts are allowed but new questions are given on the new attempt instead of the same problem over and over.

Weekly tests have limited attempts to provide a true assessment of skills. If students are not satisfied with their first attempt, they may try one more time, but there will be no additional resets. The score will be an average between the two attempts. (The second test will have different questions.) Feedback is given after the test is completed.

Enter the glass area (in^2) and the glass cost per square inch ($/in^2) into the Glass Price Calculator. The calculator will evaluate the Glass Price. ## Glass Price Formula The following two example problems outline the steps and information needed to calculate the Glass Price. GP = GA * GCSI Variables: • GP is the Glass Price ($)
• GA is the glass area (in^2)
• GCSI is the glass cost per square inch ($/in^2) To calculate glass price, multiply the glass cost per square inch by the glass area. ## How to Calculate Glass Price? The following steps outline how to calculate the Glass Price. 1. First, determine the glass area (in^2). 2. Next, determine the glass cost per square inch ($/in^2).
3. Next, gather the formula from above = GP = GA * GCSI.
4. Finally, calculate the Glass Price.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

glass area (in^2) = 50

glass cost per square inch (\$/in^2) = 12

GP = GA * GCSI = ?

# Condition¶

Tag: General

This block creates a conditional node in the workflow, which can be used, for example:

• As a gate that discards incoming data or allows it to pass.
• As a switch that redirects input data to one of the two alternative output branches.

## Introduction¶

Block behavior is based on a user-defined condition 1 which can contain any of the block variables 2. When the block receives values of variables, it starts up and checks the condition. If it is met, the data is passed further. If the condition is not met, then, based on the output setting 3, the block either:

• discards the input data, or
• sends the data to alternative outputs.

### Variables¶

Configuring a Condition block requires adding variables (no variables are defined by default). These variables are then used in the condition.

Adding a variable automatically creates ports — one input and one or two outputs. For example, when you add a variable named “myvar”, the following ports are created:

• myvar input,
• myvar output, and
• else_myvar output (optional; see section Output for details).

All ports always have the same type. By default all data types are allowed. You can change the type when adding a variable, if you want to limit the allowed types.

The block does not start until it receives values of all variables, so all input ports you create by adding variables are required ports.

### Conditions¶

Any block variable can be used in the condition. When the block starts, it substitutes the received values of variables to the conditional expression and checks if the condition is met.

Conditions may include various comparisons, logical and arithmetic operators. Common ones are:

• Basic arithmetic operators (+, -, *, /).
• Modulus (%), exponent (**), floor division (//).
• Equality (==), inequality (!=), comparisons (<, >, <=, >=). Note that = is an assignment, not equality testing!
• Logical and, or and not.

Example conditions:

• Check if variable equals some value: ans == 42.
• Check the value of a string variable: status == "Success".
• Check the value of a vector or matrix component: vec[0] <= 0; m[1][2] != 1.
• Check the number of matrix rows: m.shape[0] >= 10.
• Same for columns: m.shape[1] == 3.
• Complex condition: status == "Success" or (res[1] > 0 and res[0] + res[2] < 5).

Note

For advanced users: Python syntax is allowed in conditions.

### Output¶

There are two alternative output settings for the block: discard data if the condition is not met (default), or output it to alternative ports (the “else” branch).

For example, consider the following configuration:

• Two integer variables have been added.
• Two input ports have been automatically created: x and y (you can see them in block properties).
• Two output ports: x and y.

The block compares values it receives to x and y. If the condition is met, the same values are output to the x and y ports. If the condition is not met, there is no output — values are discarded.

Compare with the following configuration:

• Two integer variables.
• Two input ports: x and y.
• Since alternative output option is selected, this configuration creates four output ports: x, y, else_x, and else_y.

If the condition is met, block behavior is the same as in previous configuration: received values are output to the x and y ports. However if the condition is not met, the values are now not discarded; instead, they are output to the else_x and else_y ports. This is an example of a simple switch configuration.

Note that you can add some other variable to use it exclusively as a condition. For example:

If the status received is "Success", active outputs are status, x and y. In any other case, active outputs are else_status, else_x and else_y. The idea is to use the status input port as a switch condition only: related outputs, status and else_status would not be connected to anything.

Note

Since names of “else” ports are generated automatically, it is possible to create a naming conflict — for example, by adding variables “x” and “else_x”. This results in a validation error, and a workflow with a Condition block configured like this does not run (pSeven will inform you about this).

Warning

If you select the redirect option, connect “else” ports to other block, and then change the output option to default, all “else” ports are automatically removed, so the links you have created are deleted (however this does not happen until you click or ).

## Examples¶

This section provides a few examples of how the Condition block can be used in real workflows.

### Status Checker¶

The Optimizer block (Optimize) is an example of a block that has a status output port. The Condition block (CheckStatus) is used to send optimization results to some post-processing block (ProcessResult) if optimization succeeded, or make the workflow output a predefined constant if optimization failed.

In this workflow, CheckStatus has “status” variable (StringScalar) and a number of variables for optimization results. In case of success, the Optimize block outputs string "Success" to Optimize.status. This port is connected to CheckStatus.success. Condition is: status == "Success".

The success branch is default, CheckStatus simply sends all results to ProcessResult. In case of failure, the optimization result is empty, so it does not need to be passed further: “else” ports are not connected, except CheckStatus.else_status which is linked to ReturnConstant.do. Thus the failure status, processed by CheckStatus, becomes a signal for the ReturnConstant block to start up and output the constant defined by its configuration.

### Configuration Switch¶

This is an example of a workflow with a simple switch added to its run configuration.

The Switch block defines a BoolScalar variable named “use_accurate”. The “else” branch is on, and condition is: use_accurate (meaning that it is met if the value specified in run configuration is True). The use_accurate input port is uplinked and appears on the Inputs pane in Run. The outputs use_accurate and else_use_accurate are used to send signals to workflow branches:

• Switch.accurate is connected to AccurateSolver. This branch is active if “use_accurate” is True and starts a heavy solver block.
• Switch.else_accurate is connected to Generate, the first block in the alternative branch. This branch is active if “use_accurate” is False. Presumably it starts another less accurate solver for quick tests.

### Fallback¶

Fallback concept is simple: if some block fails, there may be another similar block that tries to accomplish the task. The difficult part is making the fallback block to start only if the first one fails. If you simply send input data to both blocks, they start at once, but there is no point in that.

The Condition block (CheckStatus) resolves the situation by checking the first solver status. As you can see, CheckStatus receives a copy of input data from the GetData block, but this data is not output until Solver reports its status. In case of success, CheckStatus discards the data, so AlternativeSolver receives no input and does not start.

In this example the CheckStatus block works as a simple conditional gate.

## Notes¶

• Python modules os, sys and numpy are available in the conditional expression.

• If the conditional expression evaluates to a non-Boolean, then the evaluation result is converted to Boolean using the Python’s standard truth testing procedure. For example, if you set a condition like x + y where both variables are integers, it is always met unless the sum is zero (all non-zero integers are converted to True in Python).

• Since pSeven vector and matrix types are converted to numpy.ndarray (see pSeven to Python Types Conversion), if you try to set condition like vec == [1,2,3] where vec is a RealVector, block execution will fail with a message:

The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

The solution is to use tolist(): vec.tolist() == [1,2,3].

The equation of a line

 Algebra Tutor: None Selected Time limit: 1 Day

The equation of the line that goes through the point ( 3 , 2 )

and has a slopeof 3/2

Jul 24th, 2015

------------------------------------------------------------------------------------------------------------

Since the slope and a point on the line are given, we can use the point slope form of a line to find the equation of the line.

Point slope form of a line is

$y-y_0=m(x-x_0)$

where m is the slope of the line

and $(x_0,y_0)$ is a point on the line.

Here, m = 3/2  and $(x_0,y_0)$ = (3, 2).

Substituting these values in the equation, we get

$\\ y-2=\frac{3}{2}(x-3)\\ \\ y-2=\frac{3}{2}x-\frac{3}{2}\times3\\ \\ y=\frac{3}{2}x-\frac{9}{2}+2\\ \\ y=\frac{3}{2}x+\frac{-9+2\times2}{2}\\ \\ y=\frac{3}{2}x+\frac{-9+4}{2}\\ \\ y=\frac{3}{2}x-\frac{5}{2}\\$

This is the equation of the line.
