What are the primary components of a sound source ?

What are the components of the transport system in human beings? What are the functions of these components?

To a stationary man the frequency of a sound source moving towards the man appears to be

In a transformer the number of primary turns is four times that of the secondary turns. Its primary is connected to an AC source of voltage V. Then

A line source of sound of length 10 m, emitting a pulse of sound that travels radially outward from the source. The power of the source is P = 1.0.x 10^4 W What is the approximated intensity '/' of the sound when it reaches a distance of 10 m from the source?

The intensity of a point source emitting sound at distance 3 from the source is 0.707 W//m^2? What is the average power output of the source ?

A source of sound emits 200 piW power which is uniformly distributed over a sphere of radius 10 m. What is the loudness of sound on the surface of the sphere?

Velocities of three persons A,B,C and sound source S are shown in diagram.Frequency of sound source is 600 Hz and sound speed is 325m/sec.At given situation, which of the following options is / are correct :

Two sound sources shown in the figure vibrate in phase. By moving S_(1) along PS_(1) consecutive minima are heard when L_(1)-L_(2) has values, 20cm , 60cm and 100cm . What is the frequency of sound source if the speed of sound is 340 m//s ?

Figure shows two line sources of sound, S_1 and S_2 separated by a distance 4 m.The two sources are in same phase at all times.The source emit same power and their lengths are also same.A detector moves along a circle with center at S_2 and radius 3m. The wavelength of the sound is 1m.When it is at A the intensity of sound due to source S_2 only is I_0 . The intensity o sound of B due to S_1 and S_2 is :
