c) A wave is traveling along a stretched string with amplitude A and frequency f. You can tell there is energy stored in the wave because if you touch the string it whacks your hand so hard that it stings. If the amplitude of the wave is doubled, then the energy stored in a one-foot length of the vibrating string changes by a factor of

d) A wave is traveling along a stretched string with amplitude A and frequency f. You can tell there is energy stored in the wave because if you touch the string it whacks your hand sp hard that it stings. If the frequency of the wave is reduced by 1/2, then the energy stored in a one-foot length of the vibrating string changes by a factor of

e) Power is being sent down a steel cable by means of a transverse wave on the cable of amplitude A and angular frequency ω. If the tension in the steel cable is doubled, while keeping the amplitude and the angular frequency of the wave the same, then the power transmitted down the cable changes by a factor of
