A body revolved around the sun 27 times faster then the earth what is the ratio of their radii

The period of a planet around sun is 27 times that of earth the ratio of radius of planet orbit to the radius of eath ' orbit is

Two planet are revolving around the sun. their time periods of revolution and the average radii of the orbits are respectively (T_1,T_2) and (r_1,r_2) . The ratio T_1//T_2 is

The moon revolves round the earth 13 times in one year. If the ratio of sun-earth distance to earth-moon distance is 392 , then the ratio of masses of sun and earth will be

Earth is revolving around the sun if the distance of the Earth from the Sun is reduced to 1/4th of the present distance then the present day length reduced by

The mass ratio of two planets is 1:5 . They are revolving around the sun in circular paths of radii in the ratio 2:5. The ratio between the values of acceleration due to gravity on their surface is:

A planet revolves around the sun with half as fast as the earth revolves around the sun. Determine its orbital size as compared to that of the earth.
