Question

1. how does the moment of inertia help determine the layers of a celestial body?

a. it tells us the temperature of an object, so then we know the material
b. each material has its own boiling point, telling us what its made of
c. each material has its own moment of inertia, gravity, and density, meaning we can determine
a material based on that data, telling us what the layers of a celestial body are
d. the moment of inertia does not help us determine the layers of a celestial body

Explanation:

To solve this, we analyze each option:

• Option a: Moment of inertia doesn't relate to temperature measurement for material identification. Eliminate a.
• Option b: Boiling point is not related to moment of inertia. Eliminate b.
• Option c: Different materials have distinct moment of inertia, gravity, and density values. By measuring these, we can identify materials and thus determine the layers of a celestial body. This makes sense.
• Option d: Contradicts the concept that moment of inertia (along with other properties) can help in layer determination. Eliminate d.

Answer:

c. Each material has its own moment of inertia, gravity, and density, meaning we can determine a material based on that data, telling us what the layers of a celestial body are
