1 decreases, remains the same, increases
2 decreases, remains the same, increases
1 decreases
2 decreases
The correct answer is:
1) decreases
2) decreases
To answer this question, we need to understand the relationship between the force between the sun and the planet and the planet's speed as it moves away from the sun in its orbit.
According to Newton's law of universal gravitation, the force between two objects (in this case, the sun and the planet) is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
So, as the planet moves away from the sun and the distance between them increases, the force between them will decrease. This is because the distance is squared in the denominator of the equation, meaning that even a small increase in distance will result in a significant decrease in the force.
As for the planet's speed, it is determined by the balance between the gravitational force pulling the planet towards the sun and the centrifugal force pushing the planet away from the sun due to its orbital motion. As the force between the sun and the planet decreases, the gravitational force pulling the planet towards the sun becomes weaker. As a result, the planet's speed will decrease. This is because the centripetal force required for circular motion is proportional to the square of the speed. Therefore, a decrease in the force will lead to a decrease in speed.
So, to answer the question:
1) The force between the sun and the planet decreases as the planet draws away from the sun in its orbit.
2) The planet's speed decreases as it moves away from the sun in its orbit.
Therefore, the correct answers are:
1) decreases
2) decreases.
