Answer:
Either B or D. The answer itself is 2.
Explanation:
The equation for the kinetic energy would be 1/2*mv^2.
When m is doubled, we can plug in 1 and 2 to compare our answers.
Plugging in 1 for mass would give us the answer 1/2*v^2.
Plugging in 2 for mass would give us v^2. This means that the velocity was multiplied by 2, meaning that the answer is it is multiplied by 2.
I am not sure which answer is correct since there seems to be two answer choices with 2 in it, but the answer is either B or D (I will call it ABCD because I do not want to cause confusion by saying 2 multiple times).

Explanation:
Damping by inert gas is directly proportional to the molecular mass of inert gas.
Damping by inert gas is inversely proportional to the specific heat. One should consider specific heat at constant volume here as pressure will be varying. Since molecular mass is constant, the height of peak will be reduced proportional to the molecular mass.
There is an increase in temperature during detonation of pressure.
Increase in temperature difference, decreases the specific heat and therefore increases the damping.
first object gors highest
second object goes lowest.
1. What is the true density of water?
The true density of water is 1 g/cm³. (Actually, the exact density if water is not really 1 g/cm³, but a bit less (very, very little less), at 0.9998395 g/mol at 40 degree Celsius)
2. What variables change the density of water?
Temperature and purity can change the density of water.
3. How does water go against the concept of "Thermal Expansion"?
When water is a liquid, the water molecules are packed relatively close together but can slide past each other and move around freely(as stated earlier, that makes it a liquid). As the temperature increases or decreases from 4 degree Celsius, the density of water decreases.
