A group of students did an experiment to find out if the angle of impact affects the size of crater formed. They filled a basin with flour, covered the surface with coca, and dropped marbles along a 100 cm ramp. They recorded the size of the craters. Look at their data table. The students in this class used a model to simulate what happens when meteoroids hit the Moon’s surface. How are these craters and the way they are formed different from what actually happens on the Moon?

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?
