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

question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
