The given figure shows the elliptical orbit of a planet m about the sun S. If t_(1) is the time taken by the planet of move from C to D and t_(2) is the time taken by the planet to move from A to B, then the relation between t_(1) and t_(2) is [Given, area SCD = 2 (area SAB)]

The figure shows elliptical orbit of a planet m about the sun S. the shaded area SCD is twice the shaded area SAB. If t_(1) be the time for the planet to move from C to D and t_(2) is the time to move from A to B, then:

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?

The figure represents an elliptical orbit a planet around sun. The planet takes time T_(1) to travel from A to B and it takes time T_(2) to travel from C to D . If the area CSD is double that of area ASB , them

A satellite moves in elliptical orbit about a planet. The maximum and minimum velocities of satellites are 3xx10^4 m/s and 1xx10^3 m/s respectively What is the minimum distance of satellite from planet if maximum distance is 4xx 10^4 km ?

Spacemen Fred's spaceship (which has negligible mass) is in an elliptical orbit about planet Bob. The minimum distance between the spaceship and the planet is R, the maximum distance between the spaceship and the planet is 2R. At the point of maximum distance, spaceman fred is traveling at speed v_(0) . he then fires his thrusters so that he enters a circular orbit of radius 2R. what is his new speed?

A satellite is in an elliptical orbit around a planet P. It is observed that the velocity of the satellite when it is farthest from the planet is 6 times less than that when it is closest to the planet . The ratio of distances between the statellite and the planet at closest and farthest points is :
