Question

1. it takes 365.25 days for the earth to complete one revolution around the sun. Calculate the (a) period,(b) frequency,and (c) angular frequency of Earth as it revolves around the sun.

Answer 1

(a) $T=365.25\ (days)$

(b) $f=1/T=1/(365.25\cdot24\cdot3600)=3.2\cdot10^{-8}\ (Hz)$

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