A tuning fork A,marked 512 Hz, produces 5 beats per second,when sounded with another unmarked tuning fork B.If B is loaded with wax the number of beats is again 5 per second.What is the frequency of the tuning fork B when not loaded?

When a tuning fork is slightly loaded with wax,the frequency of sound produced by it will:

The sound from a mosquito is produced when it vibrates its wings at an average rate of 500 vibrations per second. What is the time period of the vibration ?

The sound from a mosquito is produced when it vibrates its wings at an average rate of 500 vibrations per second. What is the time period of the vibration?

An organ pipe of length L open at both ends is found to vibrate in its first harmonic when sounded with a tuning fork of 480 Hz. What should be the length of a pipe closed at one end,so that it also vibrates in its first harmonic with the same tuning fork?

The radius of spherical balloon is increasing at the rate 5 cm per second. At what rate is the surface of the balloon increasing, when the radius is 10 cm?

A metre-long tube open at one end, with a movable piston at the other end, shows resonance with a fixed frequency source (a tuning fork of frequency 340 Hz) when the tube length is 25.5 cm or 79.3 cm. Estimate the speed of sound in air at the temperature of the experiment. The edge effects may be neglected.

The two equal sides of an isosceles triangle with fixed base b are decreasing at the rate of 3 cm per second. How fast is the area decreasing when the two equal sides are equal to the base ?
