A source of frequency 10kHz when viberted over than mouth of a closed organ is in unison at 300K. The beats produced when temperature rises by 1K

A

30Hz

B

13.33Hz

C

16.67Hz

D

40Hz

Text Solution

Verified by Experts

The correct Answer is:
C
`f=(V)/(4l)=sqrt((gammaRT//M)/(4l)) or fpropsqrt(T)`
`(f')/(f)=sqrt((T')/(T))=(1+(1)/(300))^(1//2) square (1+(1)/(6000)) implies f'-f=(f)/(600) implies`beats produced `=(10000)/(600)=16.67Hz`.

In two experiments with a countinous flow calorimeter to determine the specific heat capacity of a liquid,an input power of 16 W produced a rise of 10 K in the liquid. When the power was doubled, the same temperature rise was achieved by making the rate of flow of liquid three times faster. Find the power lost (in W) to the surrounding in each case.
