Complete QuestionThe average distance between earth and the sun is 1.50 x10^8 km. Calculate the average speed of the Earth in its orbit in kilometres per second.

Answer:The value is

Explanation:From the question we are told that

The average distance is

The average speed is mathematically represented as

Here t is the time taken to circle round the sun which is equal to 1 year

Now converting this to seconds we have

So

Answer:The average speed of the earth in its orbit is

Explanation:The average distance between the Earth and the Sun is .

The average speed of the earth in its orbit can be found by the next equation :

(1)

Where

ris the radius andTis the period.In this case, the orbit of the Earth can be considered as a circle

() instead of an ellipse.

It takes 1 year to the Earth to make one revolution around the Sun. Therefore, its period will be 365.25 days.

Notice that to express the period in terms of seconds, the following is needed:

⇒

Then, equation 1 can be used:
