A planet is at an average distance d from the sun and its average surface temeperature is T. Assume that the planet receives energy only from the sun and loses energy only through radiation from the surface. Neglect atmospheric effects. If `Tpropd^(-n)`, the value of n is

A planet is at an average distance d from the sun, and its average surface temperature is T. Assume that the planet receives energy only from the sun, and loses energy only through radiation from its surface. Neglect atmospheric effects. If T prop d^(-n) , the value of n is

Two planets at mean distance d_(1) and d_(2) from the sun and their frequencies are n and n respectively then

The period T and mean distance R of a planet from the sun are related by

If r denotes the mean distance of a planet from the sun and T is the time period of planet, then

A planet orbits the Sun in time T at a distance of R from it. Another planet orbits the Sun in a time of 8T. What is its distance R' from the Sun.
