Answer:
(A). The magnitude of the momentum of the marble is 0.004745 kg m/s.
(B). The speed of baseball is 23.0 m/s
Explanation:
Given that,
Mass of marble = 0.0073 kg
Speed = 0.65 m/s
(A). We need to calculate the magnitude of the momentum of the marble
Using formula of momentum

Where, m = mass
v = velocity
Put the value into the formula


(B). Mass of baseball = 0.136 kg
Momentum of baseball = 3.14 kg m/s
We need to calculate the speed of baseball
Using formula of momentum


Put the value into the formula


Hence, (A). The magnitude of the momentum of the marble is 0.004745 kg m/s.
(B). The speed of baseball is 23.0 m/s
You are correct, the answer is C.
Good insulators are materials that do not allow heat, electricity, light or sound pass through easily. Materials like steel and silver (which are metals) are not good insulators because they make good conductors. They easily allow heat, electricity and the like pass through them.
Thus, the answer is letter C. Rubber.
Answer: When 
Explanation:
According to first law of thermodynamics, energy can neither be created nor be destroyed. It can only be transformed from one form to another.


= change in enthalpy
P = pressure
= change in volume
=Change in internal energy
q = heat absorbed or released
w = work done on or by the system

Thus for
, 
The heat evolved or absorbed by the system in a physical or chemical process, equal the change in enthalpy of the system when
