To double the rate at which energy is transmitted along a string,you could
A)double the angular frequency of the source.
B)double the amplitude of the wave.
C)double the tension in the string.
D)quadruple the tension in the string.
E)halve the linear density of the string.

Question

Quizplus · Accepted Answer

The energy transmitted along a string is proportional to the square root of the tension. To double the rate of energy transmission, you need to quadruple the tension, as energy transmission is proportional to the square root of tension.
