1 point A planet of mass m moves around the Sun of mass M in an elliptical orbit. The maximum and minimum distances of the planet from the Sun are ri and r2 respectively. The time period of the planet is proportional to (1+ 12) 3/2 (1+ 12) 1/2 O Option 4 O Option 2 1 + 12 (1 - 12) 3/2 O Option 1 O Option 3 1 point The specific heat Cy at constant volume of a monatomic gas at low pressure is proportional to T" where the exponent n is: O 1 1/2 -1/2 O -1
