A boy watches Dussehra celebrations from a distance and sees the effigy of Ravana burn into flames and hears an explosion after 2 second. How far was he from the effigy, if the speed of sound in air was 335 m`s^(-1)` ?

Text Solution

Verified by Experts

Here, speed of sound - 335 m `s^(-1)`: time taken for hearing explosion - 2 s. Distance travelled by the sound `335 ms^(-1)xx2s` The boy was at a distance of 670 m from the effigy

A sonometer wire under tension of 64 N vibrating in its fundamental mode is in resonance with a vibrating tuning fork. The vibrating portion of the sonometer wire has a length of 10 cm and mass of 1 kg. The vibrating tuning fork is now moved away from the vibrating wire with a constant speed and an observer standing near the sonometer hears one beat per second. Calculate the speed with which the tuning fork is moved, if the speed of sound in air is 300 m/s.

A SONAR (sound navigation and ranging) uses ultrasonic waves to detect and locate objects under water.
