What is the importance of computing the percent difference of the gravitational acceleration
The average distance between Earth and the Sun is 1.5 ✕ 1011 m.
(a)
Calculate the average speed of Earth in its orbit (assumed to be circular) in meters per second
(b)
What is this speed in miles per hour?
Please answer B
Schwarzschild radius RS of a black hole is the maximum
distance from the black hole’s center at which light cannot escape its
gravitational field. The quantity RS (with dimensions of length) is
dependent on the mass of the black hole M, the speed of light c, and
the gravitational constant G. Based on the dimensions of these four
parameters, predict an equation for the Schwarzschild radius. Hint:
G has dimensions of [L3/MT2]

- To complete this exercise, you need to know that the circumference of a circle is proportional to its radius, and that the constant of proportionality is 2π. You do not need to know either the radius of the Moon’s orbit or the radius of Earth. For purposes of this exercise, we assume that the Moon’s orbit around Earth is circular. In one trip around Earth, the Moon travels approximately 2.4 million kilometers. Another satellite orbits Earth (in a circular orbit) at a distance from Earth that is 1/4 that of the Moon. How far does this satellite travel in one trip around Earth? (Use decimal notation. Give your answer to one decimal place.) A rope is tied around the equator of Earth. A second rope circles Earth and is suspended 77 feet above the equator. How much longer is the second rope than the first?arrow_forwardTidal friction is slowing the rotation of the Earth.
