Suppose a diving board with no one on it bounces up and down in a simple harmonic motion with a frequency of 4.25 Hz. The board has an effective mass of 8.5 kg. What is the frequency, in hertz, of the simple harmonic motion of a 71.5-kg diver on the board?

answer: the answer is a

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

this is poiselle's equation from fluid mechanic in physics. mech eng
