How the length of the year is determined, (show at least one of the two ways)

The length of a year is defined by the time it takes to orbit the sun. This is determined by the orbital path and speed at which a body takes around the sun. Thus, if a celestial body moves farther from the sun, the length of the path is increased, and a year takes longer.

Explanation:

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

are there answer choices to this question? this seems like a question where you have options to choose from.
