Question

Which is an example of a scientist using a physical model to describe the solar system?

A. The scientist uses a computer to calculate the speed of each planet.
B. The scientist compares the solar system to the shape of an atom.
C. The scientist writes an equation that predicts how long the year will be.
D. The scientist uses tennis balls to show the position of the planets and Sun.

(its D btw)

Answer 1

D. The scientist uses tennis balls to show the position of the planets and Sun.

Step-by-step explanation:

In a layman's terms, the solar system is a system consisting of the sun and the planets that orbits around it. These planets are as follows; Mercury, Mars, Earth, Saturn, Venus, Jupiter, Neptune, Uranus etc.

According to this question, using a physical model to represent or describe the solar system means the use of physical objects that can easily be seen or identified. Based on this explanation, the use of tennis balls to show the position of the planets and Sun suits the physical model description of our solar system.
