If the velocity of sound is V, velocity of the observer is V_(0) and the velocity of the source is V_(s) , then the necessary condition for the Doppler effect to hold good is -

A star is moving away from the earth with a velocity of 100 km//s . If the velocity of light is 3 xx 10^(8) m//s then the shift of its spectral line of wavelength 5700 A due to Doppler effect is
