Question

It takes 365.25 days for the earth to complete one revolution around the sun. Calculate the:
a.) period
b.) frequency
c.) angular frequency of the earth as it revolves around the sun

Answer 1

$a)$ $T=365.25\cdot24\cdot3600=31557600(s)$

b) $f=1/T=1/31557600=3.2\cdot10^{-8}(Hz)$

c) $\omega =2\pi f=2\cdot3.14\cdot3.2\cdot10^{-8}=2\cdot10^{-7}(rad/s)$
