two tuning forks oscillating coherently and in phase at 1200Hz are separated by 0.35m.
a) Calculate the angles of maximum intensity on a circular wall 10m radius and centered on the forks.(angles should extend over the full range 0-360 degrees.)
b) Calculate the angles of minimum intensity.
c) What is the phase angle difference between the waves at 40 degrees lab angle?
explain how would you evaluate much accountability for AIS security falls on management in a large and a small accounting firm.
It was a dark and stormy night, when suddenly you saw a flash of lightning. Three-and-a-half seconds later you heard the thunder. Given that the speed of sound in air is about 340 m/s, how far away was the lightning bolt?
