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

The period of revolution of planet A round from the sun is 8 times that of B. The distance of A from the sun is how many times greater then tht of B from the sun ?

Answer the following questions : Let the period of revolution of a planet at a distance R from a star be T. Prove that if it was at a distance of 2R from the star, its period of revolution will be sqrt8T .

The magnetic field at a distance r from a long wire carryimg current I is 0.4 T. The magnetic field at a distance 2r is

The angular diameter of the sun is 1920". If the distance of the sun from the earth is 1.5xx10^(11) m, what is the linear diameter of the sun ?

Consider a hypothetical planet which is very long and cylinderical. The density of the planet is rho , its radius is R . What is the possible orbital speed of the satellite in moving around the planet in circular orbit in a plane which is perpendicular to the axis of planet?

The figure shows the elliptical orbit of a planet about the sun S. An ellipse is the curve obtained when a cone is cut by an inclined plane. It has two focal points. The sum of the distances to the two focal points from every point on the curve is constant. F_1 " and " F_2 are the two focal points of the ellipse . The shaded area CF_1D is twice the shaded area AF_1B. t_1 is the time taken by the planet to move from C to D and t_2 is the time to move from A to B Which laws do we understand from the above diagram and description?
