18. have a nice day hope it helps.
Explanation:
When an electromagnetic wave like light hits a material, the electrons gets emitted. The emission of electrons is called photoelectric effect. The emitted electrons are called photoelectrons. In this process the transfer of energy takes place from light to an electron.
Hence, the correct option regarding the photoelectric experiment is (A) " Light can cause electrons to be released from the surface of a metal."
Answer:
Sample B
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. Since the speed for Sample B is higher this means it has a higher temperature as well.
Answer:
Heat flows from faster molecules to slower molecules when they collide.
Explanation:
logics
