Question 10 of 10

1. PKR
When distance between earth and sun becomes half then the revolution around the sun will be completed in approx 129 days

Explanation:

The ratio of the time periods would be {new is say T1, actual is say T2}

Note that T is directly proportional to √(R^3)

T1/T2 = √([R/2]^3)/√(R^3) = 1/(2√2)

Hence T1 = T2/2√2 = 365/2√2

Which is approx 129 days.

Hope that helps.
