Answer:
The average speed of the Earth in its orbit is 4.74 km/s.
Explanation:
Distance between the Earth and the Sun ,r= 149.60 million km = [tex]149.60\times 10^6 km[/tex]
Considering the movement of Earth around the Sun follows circular path.
The circumference of circular path will be give by :
[tex]D=2\pi r=2\times 3.14\times 149.60\times 10^6 km[/tex]
Time taken by Earth to complete revolution around earth ,T= 1 year
1 year = 365 days
1 year = 31,536,000 seconds
T = 31,536,000 seconds
Speed of the Earth around the Sun :S
[tex]S=\frac{D}{T}=\frac{149.60\times 10^6 km}{31,536,000 s}[/tex]
[tex]S=4.74 km/s[/tex]
The average speed of the Earth in its orbit is 4.74 km/s.
