Answer:
Kinetic
Explanation:
Kinetic energy kicks in after potienal builds up energy
Answer:
During chemical reactions, matter is neither
created nor destroyed; it just changes form.
Explanation:

A photon above a threshold frequency has the required energy to eject a single electron, creating the observed effect.
