Answer:
impulse acting on it
Explanation:
The impulse is defined as the product between the force applied to an object (F) and the time interval during which the force is applied (
):

We can prove that this is equal to the change in momentum of the object. In fact, change in momentum is given by:

where m is the mass and
is the change in velocity. Multiplying and dividing by
, we get

and since
is equal to the acceleration, a, we have

And since the product (ma) is equal to the force, we have

which corresponds to the impulse.
The correct option is C.
From the information given above, one can easily conclude that electromagnetic Y is the strongest because, it produces the higher amount of current compare to the other electromagnets. Electromagnet W is the weakest because it produces the lowest amount of current.
All of the above, work is a measurement of energy transfer, in Joules.
Potential energy = Joules
Kinetic energy = Joules
The key thing here is that anything having to do with just energy or energy transfer is measured in joules.
