Answer:
Step-by-step explanation:
If the student wants to show what would happen to the solar system without gravity, they would redraw the model with all the planets and other celestial bodies moving in a straight line, rather than in the elliptical orbits they currently occupy. In the absence of gravity, there would be no force holding the planets in their orbits around the sun, and they would move in a straight line until they collided with another object or left the solar system entirely. The student could also depict the sun as a stationary object, as it would no longer have any planets orbiting around it.
In the redrawn model, the sun would remain in a fixed position, and the planets would move away from it in straight lines. The planets would not be able to maintain their orbits, and would eventually leave the solar system or collide with each other.
It's important to note that this model is hypothetical, as gravity is an essential force that holds the solar system together, and without it, the solar system would not exist as we know it.
