When a planet moves around the sun

Figure shows the motion of a planet around the Sun S in an elliptical orbit with the Sun at the focus. The shaded areas A and B are also shown in the figure which can be assumed to be equal. If t_(1) and t_(2) represent the time taken for the planet to move from a to b and c to d , respectively then

Length of a year on a planet is the duration in which it completes one revolution around the sun. Assume path of the planet known as orbit to be circular with sun at the centre. The length T of a year of a planet orbiting around the sun in circular orbit depends on universal gravitational constant G, mass m_(s) of the sun and radius r of the orbit. if TpropG^(a)m_(s)^(b)r^(c) find value of a+b+2c.

State whether the following statements are true or false by writing T/F against them. (a) Earth moves around Sun with a uniform velocity. (b) The motion of moon around Earth in a circular path is an accelerated motion. ( c) A uniform linear motion is unaccelerated, while a uniform circular motion is an accelerated motion. (d) In a uniform circular motion, the speed continuously changes because the direction of motion changes. (e) A boy experiences a centrifugal force on his hand when he rotates a piece of stone tied at one end of a string. holding the other end in the hand.

Planet nearest to sun is

If the angular momentum of a planet of mass m, moving around the Sun in a circular orbit is L, about the center of the Sun, its areal velocity is :

A planet is revolving around the sun in a circular orbit with a radius r. The time period is T .If the force between the planet and star is proportional to r^(-3//2) then the quare of time period is proportional to

A : During orbital motion of planet around the sun work done by the centripetal force is not zero at all points on the orbit . R : Planet is revolving around the sun in elliptical orbit .

Is the motion of earth around sun oscillatory? Why?
