A small town has decided to forego the use of electrical power and send energy through town via mechanical waves on ropes.
 
  They use rope with a mass per length of 1.50 kg/m under 6000 N tension. If they are limited to a wave amplitude of 0.500 m, what must be the frequency of waves necessary to transmit power at the average rate of 2.00 kW?
  A)
 
  24.8 Hz
 
  B)
 
  169 Hz
 
  C)
 
  60.0 Hz
 
  D)
 
  2.07 Hz
 
  E)
 
  2.00 kHz

Question 2

Planet Z-34 has a mass equal to one-third that of Earth and a radius equal to one-third that of Earth.
 
  With g representing, as usual, the acceleration due to gravity on the surface of Earth, the acceleration due to gravity on the surface of Z-34 is A)
 
  g/3.
 
  B)
 
  3 g.
 
  C)
 
  6 g.
 
  D)
