The graph represents the simple harmonic motion of a mass on a spring. A graph with displacement on the y axis and time on the x axis. There is a transverse wave form drawn from the y axis toward the right with the x axis at the equilibrium position of the wave. The top of the first crest os labeled A. The distance from the first trough to the second trough is labeled C. The height of the second crest is labeled B. The distance from the top of the crest to the bottom of the trough is labeled D. Which arrow indicates the amplitude of the motion? A B C D

Ahydroelectric plant takes energy from water and turns it into electrical energy. what are the transformations of energy in the water molecules that are used in the process of generating electricity this way?

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
