Figure shows the orbit of a planet P round the sun S. AB and CD are the minor and major axes of the ellipse. If t1 is the time taken by the planet to travel along ACB and t2 the time along BDA, then
The following figure shows the elliptical path of a planet about the sun. The two shaded parts have equal areas. If t1, t2 be the time taken by the planet to go from A to B and from C to D respectively.
The figure shows pressure versus density graph for an ideal gas at two temperature T1 and T2:
