properly elliptic orbit, the angle between 7 and v is only at the Prove that in a 2 apogee and perigee. Clue: Do so by showing v ir if and only if a 0, then T is maximized (apogee) or minimized (perigee)when 0=0 or TT

Open-Ended Response Assessment from Kepler's Laws Describe what happens to Earth’s orbit when it gets closer to the Sun.

Hello, can u please help me with this question

What affects the force of gravity more, mass or distance? Explain answer.

If a cannonball is fired from a tall mountain, gravity changes its speed all along its trajectory. But if it is fired fast enough to go into circular orbit, gravity does not change its speed at all. Explain.

Assume that you have two objects, one with a mass of 10 kg and the other with a mass of 18 kg, each with a charge of –0.017 C and separated by a distance of 2 m. What is the electric force that these objects exert on one another? Answer in uits of N.

I was not able to solve this physics problem, please help me solve it and circle your answer. Thank you.

Which of the following are, or follow directly from, Kepler's Laws of planetary motion?  Check all that apply. More distant planets move at slower speeds.   The force of attraction between any two objects decreases with the square of the distance between their centers.   The orbit of each planet about the Sun is an ellipse with the Sun at one focus.   A planet travels faster when it is nearer to the Sun and slower when it is farther from the Sun.   As a planet moves around its orbit, it sweeps out equal areas in equal times.

What is the acceleration  of  the Earth to stay in its nearly circular orbit around the Sun?  Assume the radius of the orbit is 150,000,000 km, and the time to complete an orbit is 365 days.   Pick those answers that apply.     About 6 m/s2 away from the Sun (compare to "g" near Earth which is 9.8 m/s2)     Exactly the acceleration needed to maintain a closed curved and elliptical orbit year after year.     The Earth is not accelerating, it is moving at a constant velocity.     Much smaller than "g" and away from the Sun.     About 6 m/s2 toward the Sun (compare to "g" which is 9.8 m/s2)

A planet makes 15 orbits in 60 days, what is the period of the planet is seconds?
