3why does the frequency of a wave increase as the wavelength decreases? a) because the wave speed remains constant b) because the amplitude of the wave must remain constant c) because the frequency must get larger to increase the speed d) because the wavelength must get smaller to decrease the speed elimin

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
