Question

It takes 365.25 days for Earth to complete one revolution around the sun.

Calculate the (a) period, (b) frequency, (c) angular frequency of Earth as it

revolves around the sun.

Answer 1

$a)$ $Time=365.25×24×3600=31557600(s)$

b) $f=1/T=1/31557600=3.2×10^{-8}(Hz)$

c) $\omega =2\pi f=2×3.14×3.2×10^{-8}=2×10^{-7}(rad/s)$
