Two people playing a game of table tennis make up a closed system with 12,175 j of energy. At the beginning of the game the system has 9,875 j of ME, and at the end it has 8,430 j of ME. How much of the total energy was transformed into thermal energy during the game? A. 1,445 j B. 3,745 j C. 10,730 j D. 2,300 j

so easy. just google the electromagnetic waves and it’ll pop up.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
