Question

a. what days are associated with the location of the equator and the location of the sun?

Explanation:

The question is about the days associated with the sun's position relative to the equator, which relates to the equinoxes (when the sun is directly over the equator). The March equinox (around March 20 - 21) and September equinox (around September 22 - 23) occur when the sun is at the equator, resulting in nearly equal day and night worldwide. These are the key days related to the sun's location at the equator.

Answer:

The days associated with the sun being at the equator (its location relative to the equator) are the equinoxes: the March equinox (around March 20 - 21) and the September equinox (around September 22 - 23). On these days, the sun is directly above the equator, leading to approximately equal lengths of day and night across the Earth.
