It is important to note that the direct of flow of the electricity current in the Linear Machine is anti-clockwise direction. The resultant effect of this is such that is stand at variance with the change in flux as force is going the right direction. See attached Image (Illustration I).

<h3>What is the magnitude of the current?</h3>

Recall that Force (f) = il xB

Given that Force (F) = 10N; and

Magnetic Field Density B = 0.5T

Hence,

10 = i x 0.2 x 0.5  

[Note that Width is converted to Meters from millimeters that is 200 mmm = 0.2m]

10 = 0.1i

i = 10/0.1

i = 100A

<h3>What is the Induced Voltage Across the metal bar?</h3>

Note that Vg = Vde + IR

Vg = 10 + 100 x 0.05

Vg = 10 + 5

Vg = 15v

<h3>What is the final speed of the metal bar?</h3>

The final speed of the bar is given as V

Recall that Induced Voltage is VB x L

That is:

15 = V x 0.5 x 0.2;

15 = 0.1 V

make V the subject of the formula:

V = 15/0.1

V = 150m/s

<h3>What is the status of the Machine? a motor or generator?</h3>

Given that the current being supplied is  in DC hence the machine is a generator. [Vdc x i]

<h3>What is the electric power of the source?</h3>

The electric power of the source is:

Vdc x i

= 10 x 100

= 1,000 watts

If you were blacklisted during the Red Scare, you would not be able to find work in the entertainment industry.

<h3 /><h3>What was the Red Scare?</h3>

This was a time in the 1950s where people were increasingly worried that Communists had inflitrated America and were plotting a takeover.

When people were blacklisted for being involved in Communist activity, they would be unable to find employment in entertainment as people wanted to avoid their bad publicity.

Answer:  They may be relocated for a job

There are many people in the United States that don’t tend to buy their own house and prefer to live on rent, the major reason that they do not buy their own house is because of the nature of their job. The job that they do, require a lot of moving around in the states which as a result demands for them to move frequently and in such cases many people avoid to buy a house because you cannot live in it for a long period of time.
