Academics

Q1. What is the fundamental frequency of a 0.30 m long organ pipe that is closed at one end, when the speed of sound in the pipe is 352 m/s?

Q2. A tennis ball is thrown toward a vertical wall with a speed of 22.0 m/s at the angle of 40.0° above the horizontal. The horizontal distance between the wall and the point where the tennis ball is released is 28.0 m.

a. At what height above the point of release does tennis ball hit the wall?

b. Has the tennis ball already passed the highest point on its trajectory while it hits the wall? Justify the answer.
