There is no gravitational force between Earth and Titan.
There is no gravitational force between Earth and Titan.
The gravitational force between Earth and Titan is more than that between Earth and Saturn.
The gravitational force between Earth and Titan is more than that between Earth and Saturn.
The gravitational force between Earth and Titan is less than that between Earth and Pluto.
The gravitational force between Earth and Titan is less than that between Earth and Pluto.
The gravitational force between Earth and Titan is less than that between Saturn and Titan.
The gravitational force between Earth and Titan is less than that between Saturn and Titan.
The correct statement about Earth and Titan is: The gravitational force between Earth and Titan is less than that between Saturn and Titan.
The correct statement is: "The gravitational force between Earth and Titan is less than that between Saturn and Titan."
To understand why this statement is true, we should consider the concept of gravitational force. Gravitational force is the attractive force that exists between two objects due to their mass. The larger the mass of an object, the greater the gravitational force it exerts.
Titan, being the largest moon of Saturn, has a significant mass. Therefore, it exerts a gravitational force on both Earth and Saturn. However, since Saturn is much larger and more massive than Titan, the gravitational force between Saturn and Titan is greater than that between Earth and Titan.
To determine this answer without prior knowledge, you can follow these steps:
1. Understand the concept of gravitational force and how it relates to mass.
2. Research information on the masses of the objects involved (Earth, Saturn, Titan, and Pluto if necessary).
3. Compare the masses to determine the relative strengths of the gravitational forces between different pairs of objects.
In this case, if you compare the masses of Earth and Saturn, it is evident that Saturn is much more massive. As a result, the gravitational force between Saturn and Titan is greater than that between Earth and Titan.

When automobiles are designed, engineers try to maximize their fuel efficiency. Even with modern technology, today's most efficient vehicles can only attain about 30% efficiency. That means of all the chemical energy of the fuel put into an automobile, only 30% of the fuel results in car motion. Which statement best explains why this happens?(1 point)
