select all the correct answers.\na worker is holding a filled gas cylinder still. which two sentences are true about the energy of the filled gas cylinder?\n□ it has no energy because its being held still.\n□ it has gravitational potential energy because of its height.\n□ its atoms and molecules have thermal energy.\n□ it has motion energy because it will fall if let go.\n□ its kinetic energy is being converted to potential energy.

Answer

Explanation:

Step1: Analyze energy concepts

Energy exists in different forms. A stationary object can still have energy.

Step2: Consider gravitational potential energy

The gas - cylinder is at a height above the ground, so it has gravitational potential energy given by $U = mgh$ (where $m$ is mass, $g$ is acceleration due to gravity, and $h$ is height).

Step3: Consider thermal energy

The atoms and molecules in the gas inside the cylinder are in constant random motion, so they have thermal energy.

Step4: Analyze motion energy

It has no motion energy (kinetic energy) as it is held still. The statement about it having motion energy because it will fall if let go is incorrect as it is not in motion currently. Also, there is no conversion of kinetic to potential energy as it is stationary.

Answer:

It has gravitational potential energy because of its height. Its atoms and molecules have thermal energy.
