A wave of frequency f is transmitted on a string with tension T.If the tension is increased by a factor of 4 and the frequency and amplitude are unchanged,the power transmitted changed by
A)1/2
B)1/4
C)2
D)4
E)1

Question

Quizplus · Accepted Answer

The power transmitted by a wave on a string is proportional to the square root of the tension. If the tension is increased by a factor of 4, the power increases by a factor of 2.
