A person hums into the top of a well (tube open at only one end) and finds that standing waves are established at frequencies of 37.9, 63.2, and 88.4 Hz. The frequency of 37.9 Hz is not necessarily the fundamental frequency. The speed of sound is 343 m/s. How deep is the well?

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?
