Make sure that "Scientific Notation" is selected for Force Values. Express your answer in scientific notation, ex 5.208 x 10-9 N What is the force of gravity acting on the spheres under the following conditions? Mass of 1 = 25 kg Location of 1 = 4 m Mass of 2 = 25 kg Location of 2 = 6 m

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?

It is really hard for me right know
