A line between a planet and the sun sweeps out two equal areas at different places as it moves along its orbit. Which factor remains constant as this happens?(1 point) Responses the distance the planet moves along its orbit while it sweeps out the area the distance the planet moves along its orbit while it sweeps out the area the time required to sweep out the areas the time required to sweep out the areas the distance from the sun to the planet while it sweeps out the areas the distance from the sun to the planet while it sweeps out the areas the planet’s speed as it sweeps out the areas
The factor that remains constant as the planet sweeps out two equal areas is the second option, the distance the planet moves along its orbit while it sweeps out the area.
An asteroid approaches Jupiter and is slung around into a new trajectory across the solar system. Which of the following are possible? Select the three correct answers.(2 points) Responses The asteroid slows down as it passes around Jupiter. The asteroid slows down as it passes around Jupiter. The asteroid falls into an irregular orbit around Jupiter. The asteroid falls into an irregular orbit around Jupiter. The asteroid adopts an unusual orbit around the sun, such as an egg shape. The asteroid adopts an unusual orbit around the sun, such as an egg shape. The asteroid spirals into the sun. The asteroid spirals into the sun. The asteroid continues out of the solar system. The asteroid continues out of the solar system. The asteroid enters a stable elliptical orbit around the sun.
The three correct possibilities are:
1. The asteroid falls into an irregular orbit around Jupiter.
2. The asteroid adopts an unusual orbit around the sun, such as an egg shape.
3. The asteroid continues out of the solar system.
Which did Kepler notice about planetary motion that caused him to propose Kepler’s first law of orbital motion?(1 point) Responses The distance between Mars and the sun is constant. The distance between Mars and the sun is constant. The planets have circular orbits. The planets have circular orbits. The distance to the sun varies. The distance to the sun varies. Most planets have highly elliptical orbits.
The correct answer is: The planets have circular orbits. Kepler noticed that the planets have circular orbits, which led him to propose Kepler's first law of orbital motion.
Which statements about the geocentric model are false? Select the two correct answers.(1 point) Responses It shows Earth at the center of the solar system. It shows Earth at the center of the solar system. It shows the orbits of the planets as circular. It shows the orbits of the planets as circular. It shows the Sun at the center of the solar system. It shows the Sun at the center of the solar system. It explains why Mars appears to move backward for a few months approximately every two years.
The two correct statements that are false about the geocentric model are:
1. It shows the orbits of the planets as circular.
2. It explains why Mars appears to move backward for a few months approximately every two years.
In the geocentric model, the planets' orbits were depicted as perfect circles and the retrograde motion of planets like Mars could not be explained.
