A highly sensitive device for measuring the acceleration due to gravity (a gravimeter) is carried to the top floor of a skyscraper. The top floor is 705 m above the street. Part A Part complete How does the magnitude of the acceleration due to gravity at the top of the tower compare to its value at street level

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
