Two loudspeakers are mounted on a merry-go-round whose radius is 9.01 m. When stationary, the speakers both play a tone whose frequency is 100.0 Hz. As the drawing illustrates, they are situated at opposite ends of a diameter. The speed of sound is 343 m/s, and the merry-go-round revolves once every 20.0 s. What is the beat frequency that is detected by the listener when the merry-go-round is near the position shown?

W hat is the velocity of the gasoline in the tube
The spring of the pressure gauge has a force constant of1000 n/m and the piston has a diameter of 2.00 cm as the gauge is lowered into water, what change in depth causes piston to move in by 0.50 cm.
A wheel 65 cm in diameter accelerates uniformly from 215 rpm to 390 rpm in 6.0 s. How far will a point on the edge of the wheel have traveled in this time.
The temperature of the air in a resonator is 15°C, when a tuning fork vibrates at one end, the spacing between tow successive resonances is found to be 50 cm. find the frequency of the tuning fork.
A 1.0--tall vertical tube is filled with 20o water. A tuning fork vibrating at 574 is held just over the top of the tube as the water is slowly drained from the bottom.
