Answer: A device that uses electricity and magnetism to create motion is called a <u> motor .</u> In a reverse process, a device that uses motion and magnetism can be used to create <u>electricity</u>

Explanation:

A motor is a device that uses electricity and magnetism converts it to mechanical energy. A current carrying wire is placed between two magnets. A force is produced which causes the current carrying wire to rotate. Motor is used to pull water in pipelines.

In the reverse process, a generator uses motion and magnetism to produce electric current. When a conducting wire is placed between changing magnetic field, electromotive force is induced which causes electricity to flow in the wire.

balu736 [363]

To solve this problem it is necessary to apply the concepts related to momentum, momentum and Force. Mathematically the Impulse can be described as

I = F*t

Where,

F= Force

t= time

At the same time the moment can be described as a function of mass and velocity, that is

P = m\Delta v \rightarrow P=m(v_1-v_2)

Where,

m = mass

v = Velocity

From equilibrium the impulse is equal to the momentum, therefore

I = p

Ft = m(v_1-v_2)

PART A) Since the body ends at rest, we have the final speed is zero, so the momentum would be

p=m(v_1-v_2)

p = 75*0.15

p = 1125Kg\cdot m/s

Therefore the magnitude of the person's impulse is 1125Kg.m/s

PART B) From the equation obtained previously we have that the Force would be:

Ft = m(v_1-v_2)

F(0.025)= 1125

F= 45000N

Therefore the magnitude of the average force the airbag exerts on the person is 45000N
