I have 3 questions I can't figure out please help.
(1.)The Sears Building in Chicago sways back and forth with a frequency of about 0.10 Hz. What is its period of vibration?
(2.)Sound with a frequency of 261.6 Hz travels through water at a speed of 1435 m/s. Find its wavelength in water.
(3.)What is the relationship between the amplitude of a wave and the energy carried?

1) period = 1/frequency
2)speed = wavelength X frequency
wavelength= speed/frequency
3)I think Energy is proportional to the Amplitude^2 maybe

T = 1/0.10 s = 10 s
Wavelength = 1435/261.6 = 5.49 m
3) E is directly proportional to Amplitude squared.
