A man is standing on the platform and one train is approaching and an another train is going away with speed of 4 m/s, frequency of sound produced by the trains is 240 Hz. What will be the number of beats heard by him per second? (Take velocity of sound to be 300 m/s)

A whistle producing sound waves of frequencies 9500 Hz and above is approaching a stationary person with speed v ms-1. The velocity of sound in air is 300 ms-1. If the person can hear frequencies up to a maximum of 10,000 Hz, the maximum value of v up to which the person can hear the whistle is

 
15 ms-1
15/ ms-1
15 ms-1


30 ms-1

Directions: In the following question, Statement-1(Assertion) is followed by Statement-2 (Reason). The question has the following four choices out of which only one choice is correct.

Statement - 1: If an observer moves towards a stationary source of sound, the frequency of the sound as heard by him is greater than the actual frequency.
Statement - 2: The apparent increase in frequency is due to the fact that the observer intercepts more waves per second when he moves towards the source.

 
Statement - 1 is true, Statement - 2 is true and Statement - 2 is the correct explanation for Statement - 1.
Statement - 1 is true, Statement - 2 is true but Statement - 2 is not the correct explanation for Statement - 1.
Statement - 1 is true, Statement - 2 is false
Statement - 1 is false, Statement - 2 is true

Speed of sound in a gas is inversely proportional to square root of its molar mass at a given temperature. N2 has molar mass 28 and He has molar mass 4. Thus (c) is the correct answer.
