A.
The Moon and Earth are held together by gravity. The Earth is much more massive than the Moon causing the Moon to orbit Earth. Stars and Planet form as a result of gravitagional collapse of accreting material.
Spinning is due to the tidal force between Earth and Moon, gradually slowing its initial rotation untill the current more stable situation evolved. Tidal force continues to affect the Earth Moon system they exert enough frictional force on the Earth so that some of its angular momentum is being transferred slowly to the Moon.
Moon Fact Questions A. Why is the Earth-Moon system spinning? B. How does the Moon stabilize...
The tidal forces between the Earth and the Moon slowed down the Moon's rotation about its own axis until the rotation period became equal to the Moon's orbital period around the Earth as we observe today. The same effect is also slowing down the Earth's rotation about its own axis and increasing the separation \(D\) between the Moon and the Earth at a rate of \(\Delta D / \Delta t=3.8 \mathrm{~cm}\) per year. In this problem, you can ignore the...
Use a pencil to shade in the dark side of the moon in each of these eight moon posi- tions in Figure 26-1. Then shade the circles in Figure 26-2 to show how the moon would appear from Earth at each position in its orbit Crescen-) law> pb .

) Distance from Earth to Moon is about 2.39×105 miles. Assuming that a spacecraft can take off from Earth, attain escape velocity (see part (C)) and directly get to the Moon and land, what would be the time taken for travel to the Moon? Apollo 11 astronauts reached Moon in 4 days, 6 hours and 45 minutes in July 1969. It is not really practical to go to Moon in one shot. One way is to get a craft to...

Which of the following theories justifies the tilt in the spin axis of the earth? a) capture theory d) all of the above b) twin formation theory enone of the above c) fission theory 57. What...
You are an observer in a 100-m long spacecraft traveling from the earth to the moon at 0.8c. (a) What is the proper length of the spacecraft? (b) For a proper time interval of 1 sec., the relativistic time interval for the spacecraft measured from the earth reference frame would be: (c) Time dilation does not apply to all time-dependent physical and biological processes. T/F? (d) What is the relativistic length, DL measured from the reference frame of earth? (e)...

Please answer the following physics questions: 1.) Consider a simple pendulum (no friction). Does the angular acceleration of the mass remain constant during its motion? If not, then how does the angular acceleration change? In which part of the motion, the angular acceleration of the pendulum would be equal to zero? 2.) A pendulum has th period equal to 1,000 s on the Earth. What would be the period of the same pendulum when measured on the surface of the...
For a non-rotating Earth, if orbital size stays the same but the inclination increases, how does the ground track change? A) It becomes more spread out B) It becomes less spread out C) It reaches a higher latitude D) It reaches a lower latitude E) It has no effect
