The fundamental frequency in an open organ pipe is equal to the third harmonic of a closed organ pipe. If the length of the closed organ pipe is 20cm, the length of the open organ pipe is :-
(c) : In vertical simple harmonic motion, maximum acceleration (aω2) and so the maximum force (maω2) will be at extreme positions. At highest position, force will be towards mean position...
The correct answer is
(c) 2 v
EXPLANATION:
Between one extreme position to another i.e. in half the time period the K.E. increases from zero to maximum (at the mean position) and again...
The correct answer is (a) v
EXPLANATION:
The time taken by the wave in moving one wavelength is exactly the same as in moving the cork one oscillation. Hence the frequency of...
(a) longitudinal stationary waves
EXPLANATION:
An organ pipe open at both ends contains sound waves which are longitudinal waves, so the option (c) and (d) are not true. When the waves enter...
The correct answer is (c) v
EXPLANATION:
When a tube of length L open at both ends has a fundamental frequency ν, then v = V/2L where V is the velocity of...
(b) The National Social Assistance Programme (NSAP) which came into effect from 15th August, 1995 represents a significant step towards the fulfillment of the Directive Principles in Article 41 (Right...
