Answer:
1. Who gathered the data that showed planets traveling in elliptical paths around the sun?
2. Who discovered elliptical orbits?
3. Who explained them?
Explanation:
1. Tycho Brahe was the one that gathered data.
2. Johannes Kepler discovered it using Tycho Brace’s Data.
3. I believe it was Johannes Kepler because he created 3 laws of it.

Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that the acceleration due to gravity is given as



now we know that



now we have


Part b)
As we know that the escape speed is given as




<u>Answer</u>
3.44 m/s
<u>Explanation</u>
The motion apply the equations of Newton's law of motion. The ball is acceleration is -9.8 m/s² (acceleration due to gravity. It is negative because the ball is going against gravity, so it is decelerating).
The first equation of Newton's law of motion is;
V = U + at
Where V is the final velocity, U is the initial velocity, a is acceleration and t the time taken.
V = 25 + (-9.8 × 2.2)
= 25 - 21.56
= 3.44 m/s
Answer:
There is no short answer.
Explanation:
In theory, the gravitational pull between the planets depends on their total mass and the distance between them. The sun has a mass of
kg, Jupiter has a mass of
kg and Earth has a mass of
kg.
Earth is closer to Jupiter than it is to the sun. The other planets that are behind jupiter are gone so that means the sun's pulling force's effect on jupiter is increased drastically since there is no force the balance that and that means that jupiter is going to get closer to earth.
The new center of mass of the new solar system is roughly located between earth and the sun, closer to earth.
I hope this answer helps.
