Answer:
If only internal forces are doing work (no work done by external forces), then there is no change in the total amount of mechanical energy. The total mechanical energy is said to be conserved. ... In these situations, the sum of the kinetic and potential energy is everywhere the same.
Explanation:
Answer:
I'm pretty sure it's 49 but then again I don't know
Answer:
Model will be classified as a physical model since it is demonstrating a model in real life.
Explanation:
The average kinetic energy of a gas particle is directly proportional to thetemperature. An increase intemperature increases the speed in which the gas molecules move. Allgases at a given temperature have the same average kinetic energy. Lightergas molecules move faster than heavier molecules.
Answer:
(C)
Explanation:
Because the photons being different makes them have different amounts of energy, they both with have a precise and different energy from each other.
