Steve is whirling a rubber cork, tied with a string to his finger, over his head as shown in the figure. the motion of the cork is similar to the motion of a planet in the solar system around the sun. which force in the solar system is similar to the tension in the string?

The tension in the string corresponds to the gravitational attraction between the Sun and any planet.

Explanation:

While Steve is whirling a rubber cork, it developes a situation which is similar to the Solar System. In the rubber cork movement, there's "circular" motion which is possible thanks to the string, that is, the string works as "attraction force", allowing the system to maintain its movement.

Now, in the Solar System, the graviational force is like the string, it's the physical magnitude that maintains planets on their movements, attached to the Sun someway.

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

i think the answer is a and b

i wish you luck
