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

At 16^@C , two open organ pipes , when sounded together, produce 34 beats in 2 seconds. How many beats per second will be produced, if the temperature rises to 51^@C ? Neglect the increase in the length of the pipes.

A tuning fork of frequency 200Hz is in unison with a sonometer wire . The number of beats heard per second when the tension is increased by 1% will be

An organ pipe, open from both end produces 5 beats per second when vibrated with a source of frequency 200 Hz . The second harmonic of the same pipes produces 10 beats per second with a source of frequency 420 Hz . The frequency of source is

A source of sound gives 5 beats when sounded with another source of frequency 100 Hz. The second harmonic of the source together with a source of frequency 200 Hz gives 10 beats s^(-1) . What is the frequency of the source?

Find the increase in mass of water when 1.0 kg of water absorbs 4.2 xx 10^3 J of energy to produce a temperature rise of 1K .
