Một chất điểm đang di chuyển trên đường cong y = x − (x 2/400), trong đó x và y tính theo f t.

Nếu thành phần vận tốc theo phương x không đổi là vx = 2(f t/s), xác định độ lớn của vận tốc và gia tốc

chất điểm khi x = 20(f t)

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
