A decrease in mass will decrease an objects weight because
weight = mass x gravitational constant
The gas would also decrease in size since the container lost gas to decrease the size of the container.
Gamma rays are the highest energy EM radiation and typically have energies greater than 100 keV, frequencies greater than 1019 Hz, and wavelengths less than 10 picometers.

<u>Hydroelectric power,</u> also called hydropower is the electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy.
Well, the acceleration is the difference of speeds divided by the time period.
