I can't really answer this question without giving me any limits to the possibilities of the answers. However, I found a similar problem with a given set of choices. I think the answer is plasma. The medium that has the highest conductivity must be electric or ionized in nature. Since plasma is a very hot ionized gas, then it would be the most conductive out of all the choices.
(mu s) is the coefficient of kinetic friction, <span> (mu k) is a normal force,</span>
Answer:
Inertia depends upon the force applied .
The anwser would be A

Answer:
106.7 N
Explanation:
We can solve the problem by using the impulse theorem, which states that the product between the average force applied and the duration of the collision is equal to the change in momentum of the object:
where
F is the average force
is the duration of the collision
m is the mass of the ball
v is the final velocity
u is the initial velocity
In this problem:
m = 0.200 kg
u = 20.0 m/s
v = -12.0 m/s
Solving for F,
And since we are interested in the magnitude only,
F = 106.7 N
