For a moon orbiting its planet, r p is the shortest distance between the moon and its planet and r a is the longest distance between the moon and its planet. What is a moon’s orbital eccentricity if r p is equal to 0.27r a?
A. 0.57
B. 0.27
C. 0.48
D. 0.65

Answer:

Explanation:

The eccentric formula for ellipse can be calculated using

e = (r_a - r_p) / (r_a + r_p)

r_a is the longest distance between the moon and its planet

r_p=0.27 r_a is the shortest distance between the moon and its planet

Then,

e = (r_a - r_p) / (r_a + r_p)

e = (r_a - 0.27 r_a) / (r_a + 0.27 r_a)

e = 0.73r_a / 1.27 r_a

e = 0.57

This is the moon orbital eccentric

Answer:

1. The greater the distance, the slower the orbital velocity

2.The amount of the gravitational force doubles

3.an ellipse that is almost circular

4.0.57

5.The asteroid spirals into the sun, The asteroid continues out of the solar system, The asteroid enters a stable elliptical orbit around the sun

6.The planets move in perfect circles, The Sun is at the center, The stars are fixed to an outer sphere

7.1/√5v

8.The distance to the sun varies

10.the time required to sweep out the areas

11.It explains why Mars appears to move backward for a few months approximately every two years, It shows the Sun at the center of the solar system

12.T^2=r^3

14.Gravitational force increases as the mass of objects increases, The theory applies to all objects in the universe, Gravitational force increases as the distance between objects decreases

Explanation: i just took the test and there 100% of you dont beleave me find out for your self its ok to disagree
