3: C the earth's axis is angled meaning the sun is closer or farther to/from the earth during season changes
4: False a revolution is how long the earth takes around the sun
Answer:
1 Hz
Explanation:
For rope fixed on both ends the length corresponds to λ/2 (λ is wavelength)\
Thus L = λ/2
=> λ = 16 m
We know that frequency and wavelength are related as
f x λ = v where f is frequency and v is speed of the wave
thus f = v/λ
f = 16/16 =1 Hz
The answer to your question is kidneys
