Kepler and newton studied the movement of planets. kepler studied the speed of the planets while newton studied the forces that kept the planets in place. which of these statements best explains why the two scientists proposed different theories about the planets? they had different goals. they studied different models. they used different sets of data. they misinterpreted their findings.

They studied different models.

Explanation:

Newton's laws pertained to the study of objects based on the concepts of gravity. Forces between the planetary bodies were give by the universal law of gravitation of Newton.

Kepler's 3 laws defined the orbits  of the planets, and also a way to relate their orbital radius to their time periods and the velocity law. According to the law of speed, if a planet is close to the Sun it will move faster and if it is farther away from the sun, it slows down and will have lesser speed.

According to Newton's gravitational law , a planet that is closer to the sun experiences a greater force or gravitational pull and vice versa.

answer: b.

explanation:

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
