Question

1. A diagram that shows the sun at the center of the solar system is known as a? A) geocentric model. B) heliocentric model. C) universe model. D) earth moon sun model. 2. Why do the planets not travel in a straight path?. A) The forces of inertia and gravity cause them to move in a elliptical orbit around the Earth. B) The forces of inertia cause the planets to move in curved paths around the sun. C) the forces of inertia cause the planets to move in curved paths around the sun. D) the forces of gravity and inertia combine to produced elliptical orbits around the sun. E) all of above.

Answer 1

1. B) heliocentric model.

2. D) the forces of gravity and inertia combine to produced elliptical orbits around the sun.

Step-by-step explanation:

Heliocentric model is the solar system model with sun at its center and planets and moon revolving about it. It was proposed by Nicolaus Copernicus.

Planets tend to move in straight path due to inertia of motion but are pulled in the orbit due to force of gravity. The planets revolve around the sun in elliptical orbits. The combination of inertia and gravitational force keep them in elliptical paths.

Answer 2

Sun at the center of the solar system is known as a
heliocentric model
the model in which earth and planets revolve around the sun which is at the center
so i conclude option B is correct
hope it helps
