WILL GIVE BRAINLIEST IF CORRECT Which statement best explains the net transfer of energy that is about to happen in this photo? A. The racket and the ball will both lose potential energy. OB. The racket will gain potential energy, and the ball will lose kinetic energy C. The ball will gain kinetic energy, and the racket will lose kinetic energy O D. The racket and the ball will both gain kinetic energy.

May someone explain how to do this question?

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth

Oxygen and hydrogen gas are at the same temperature t.what is the ratio of kinetic energies of oxygen molecule and hydrogen molecule if oxygen is 16 times heavier than hydrogen.
