how does the sun rise and set
a.earth orbit around the sun
b.The sun is center of solar system
c.earth rotates on it tilted axis and orbit around the sun at the same time​

Answers

Answer:

c. earth rotates on it tilted axis and orbit around the sun at the same time​

Explanation:

Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.

This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun. Thus, this makes us to experience day and night (sun rise and sun set) due to the rotation of planet about its axis.

Hence, the sun rise and set because the earth rotates on it tilted axis and orbit around the sun at the same time​

Tarzan is swinging back and forth
on a 6.25 m long vine. What is the
period of his oscillation?
(Unit = s)

Answers

Answer:

5.02s

Explanation:

I got it right in acellus :)

The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.

Calculation of the period:

Since

Length L = 6.25 m

g = 9.8 m/s²

So,

T = 2π√(L/g)

T = 2π√(6.25 / 9.8)

T = 5.01 sec

Hence, The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.
