Answer:
Just as the angles of the sun, moon and Earth affect tidal heights over the course of a lunar month, so do their distances to one another. Because the moon follows an elliptical path around the Earth, the distance between them varies by about 31,000 miles over the course of a month.

<span>its speed acceleration and velocity</span>
Answer:
Explanation:
at collision, m has a velocity of √2gR
The center of mass of the system has a velocity of
m(√2gR) + 3m(0) = (m + 3m)v
v = ¼√2gR
The stationary mass (3m) will depart at twice the system center of mass velocity
v(3m) = ½√2gR ANSWER B
The relative velocity before the collision will be the negative of the relative velocity after the collision.
v(m) = ½√2gR - √2gR = -½√2gh ANSWER A
m will rise to a height of v²/2g = (-½√2gR)²/2g = 0.25R
Your body is accelerating at the same speed as the car. If the car stops and there is nothing to restrain you, the inertia will cause your body to keep traveling at the same speed and you will fly forward, possibly through the windshield.
Answer:
The magnetic field doubles as well
Explanation:
in an EM wave, the magnitude of the electric field is proportional to the
magnitude of the magnetic field, and the proportionality constant is c, the
speed of light!
That is : E = cB
