The Earth completes one revolution around the sun, and its average distance from to the sun during one revolution is 94.4 million miles. Assuming that Earth's orbit is a perfect circle with the sun at its center, calculate the magnitude of the Earth's average velocity (in m/s) over a period of one year.

4817 m/s

Explanation:

Velocity is the time rate of change of displacement. The S.I unit of velocity is m/s. Velocity is the ratio of displacement to time, it is given by the formula:

Velocity  = displacement / time

Average velocity is the ratio of the total distance travelled to the total time taken. It is given by the formula:

Average velocity = total distance travelled / total time taken

Given that the one revolution = 94.4 million miles, time taken = 1 year, hence:

1 mile = 1609.34 m

94.4 million miles =

1 year = 31536000 s

Therefore:

Average velocity = total distance travelled / total time taken

Average velocity = 1.5 * 10¹¹ m / 31536000 = 4817 m/s

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
