Question

. The earth revolves around the sun in the counterclockwise direction, completing one full revolution about every 365 days. In reality the orbit is elliptical (with an eccentricity of 0.0167), but we’ll pretend that the orbit is a perfect circle. How many revolutions per day does the earth make around the sun? What is the angular velocity ωSE (radians/day) of the earth around the sun?

Answer 1

Step-by-step explanation:

The earth makes in 365 day 1 revolution

The earth makes in 1 day 1 / 365 revolutions

1 / 365 revolution per day

n = 1 / 365 per day .

n is called frequency of revolutions .

Angular velocity = 2π n

= 2 π x 1 / 365

= .0172 radian / day
