From keplers law of areas we know that the speed of the planet will be at its maximum when the planet is closest to the star.
So at point be velocity will be at its maximum hence the kinetic energy will be too
Since energy is conserved, this kinetic energy will be stored as potential energy when it goes to the farthest point (A)
At point A the potential energy will be at maximum
The kinetic energy will start to increase from point C
The potential energy will start to increase from D
The total energy will remain same, so no point in orbit will denote an increase in total energy
Answer is B A C D

Planet X has a mass of 4.86 x 102 kg and it orbits 1.09 x 108 km from a star with a period of 225 days. What is the angular momentum of the planet around its star? Answer in units of kg m²/sec. Due to its large distance from its star, you can treat the planet as a point mass in its circular motion around the star. O 1.86 x 1040 O 1.61 x 1039 O 2.93 x 1039 O...

Cart mr 6- A planet of mass m and radius r orbits a star at a distance R (between their centres) with an angular velocity Wort = 2 rad/s. The planet also rotates around its own axis with an angular velocity of spin = 10 rad/s. The mass of the star is M-1000m. The moment of Star -R 00 inertia of a solid sphere is I = 2 mr 2- Calculate the total angular momentum L of the planet in...

Each of the following diagrams shows a planet orbiting a star. Each diagram is labeled with the planet's mass (in Earth masses) and its average orbital distance (in AU). Assume that all four stars are identical. Use Kepler's third law to rank the planets from left to right based on their orbital periods, from longest to shortest. If you think that two (or more) of the diagrams should be ranked as equal, drag one on top of the other(s) to...
