What is the angle between a wire carrying an 8.40 A current and the 1.20 T field it is in, if 50.0 cm of the wire experiences a

magnetic force of 2.55 N? ° (b) What is the force (in N) on the wire if it is rotated to make an angle of 90° with the field? N

Answer:

A. 30.38°

B 5.04N

Explanation:

Using

F= ILBsin theta

2 .55N= 8.4Ax 0.5mx 1.2T x sintheta

Theta = 30.38°

B. If theta is 90°

Then

F= 8.4Ax 0.5mx 1.2x sin 90°

F= 5.04N

14. Determine the kinetic energy of a 1000-kg roller coaster car that is moving with a speed of
ElenaW [278]

Answer:

<h2>200,000 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 1000 \times  {40}^{2}  \\  = 500 \times 400

We have the final answer as

<h3>200,000 J</h3>

Hope this helps you

A proton with an initial speed of 400,000 m/s is brought to rest by an electric field. Did the proton move into a region of high
Anton [14]

A proton is initially moving at high speed

v = 400000 m/s

so here initially proton is having high speed and high kinetic energy

now this proton comes to rest by external electric field

so the potential energy of proton will increase or we can say that kinetic energy will convert into electrostatic potential energy

so here the proton must have to move at higher potential region

so here correct answer must be

b. Because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.

The ____ is a measure of the number of waves that pass a point in a given amount of time
nikitadnepr [17]

The (frequency of the wave multiplied by the number of seconds
in a given amount of time)
is the measure of the number of waves that
pass a point in that amount of time.

If you had said "in one second" instead of "in a given amount of time,
then the word in the blank would simply be frequency.
