Acar is travelling at a velocity of 15 m/s due north speeds up uniformly to a velocity of 30 m/s in 3 seconds. calculate its accelartion.

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?

The strong nuclear force acts over a small distance than the electrostatic force. true or false
