A,B,C are three planets with the same mass,then it means they have also the same gravity,so what matters here is the distance between the Sun,more exactly,their orbits. ⇒ <span>The shorter the distance from the Sun, the more a planet completes an orbit. ⇒ Correct affirmation : </span>Planet A will take the shortest time to complete an orbit, while planet C will take the longest time.
The first affirmation is false because the planet A is the closest to Sun,so logically,it will complete the orbit faster than the others.
The affirmations 3 and 4 are incorrect because their gravity is equal and because the distance between the planets and the Sun <span>differs from one planet to another. </span>
They form when wind blows over the surface of the ocean. Wind energy is transferred to the sea surface. Then, the energy is carried through the water by the waves. This gives waves the energy to erode the shore.
