The domains in a temporary magnet easily lose alignment, but the domains in a permanent magnet keep their alignment.
Answer: B: The car is speeding up in the same direction as it is traveling.
Explanation:
I took the test and got it right
Answer:
I = 0.96 A
Explanation:
No of electrons, 
Time, t = 3 ms = 
We need to find the electric current. We know that electric charge per unit time is equal to the electric current.
q = ne (Quantization of electric charge)
So, the electric current is 0.96 A.
Answer:
(c) position
Explanation:
From the work-energy theorem, the workdone by a force on a body causes a change in kinetic energy of the body.
But, remember that the work done (W) by a force (F) on a body is the product of the force and the distance d, moved by the body caused by the force. i.e
W = F x d
This distance is a measure of the position of the body at a given instance.
Therefore, the work done is given by the force as a function of distance (or position).
The answer is c you got to look for answers that make sense
