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


    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.
