As of September 2022 these are the correct answers for Gravity and Orbits Quick Check Connexus 7A. If you do not trust this, that is your problem NOT mine.
I understand that you are giving the correct answers for a Gravity and Orbits Quick Check. However, from your list of questions, it seems like you are looking for explanations rather than just the answers. Let me explain each of these concepts to you:
1. The size of a small pile of bread crumbs: The size of a small pile of bread crumbs refers to its mass or weight. Mass is a measure of the amount of matter an object contains. In this context, the size of the pile of bread crumbs is referring to the object's mass.
2. When an object is at sea level: When an object is at sea level, it means that the object is located at the average height of the surface of the ocean. In terms of gravity, being at sea level means that the object is closer to the center of the Earth. This proximity to the Earth's center affects the strength of gravity acting on the object.
3. Toward the center of the Earth: Gravity is a force that pulls objects towards the center of the Earth. The direction of the force of gravity is always directed toward the center of the Earth. This means that if you were to drop an object, it would fall straight down towards the center of the Earth due to the gravitational force.
4. Sun's gravitational pull: The Sun's gravitational pull refers to the force exerted by the Sun on objects in its vicinity. Just like the Earth, the Sun has its own gravitational field that attracts objects towards it. The strength of the Sun's gravitational pull depends on the distance between the object and the Sun. Objects closer to the Sun experience a stronger gravitational pull compared to those farther away.
