Answer:
B
Explanation:
It's Scientifically proven
I believe it would be due to the weight and/or friction.
Actually the
Kinetic Energy, which is also known as the energy of motion is directly
proportional to temperature. So the higher the temperature is, the faster the gas
particles move so they have possess more kinetic energy.
This temperature is in
absolute units so we convert to Kelvin:
200 C = 473.15 K
100 C = 373.15 K
So the amount increase
is:
473.15 / 373.15 =
1.268
<span>It will increase by a
factor of 1.268 or 126.8%</span>

Answer:
a) (Positive), b) . The collision is not perfectly elastic.
Explanation:
a) The collision can be described by the Principle of Momentum Conservation and Principle of Energy Conservation:
The final velocity of the rock is:
b) The coefficient of restitution is the best criterion to distinguish elastic collsions from inelastic collisions, such criterion is the ratio of final energy of the system to initial energy of the system:
The collision is not perfectly elastic.
