Question

which of the following, taken by itself would be most effective in increasing the rate at which energy is transferred by a wave traveling along a string​

Answer 1

Answer:

Doubling the amplitude of the wave causes the power to be larger by a factor of 4. In (a), halving the linear mass density of the string causes the power to change by a factor of 0.71 - the rate decreases. In (b), doubling the wavelength of the wave halves the frequency and causes the power to change by a factor of 0.25 - the rate decreases. In (c), doubling the tension in the string changes the wave speed and causes the power to change by a factor of 1.4 - not as large as in part (d).
