Answer:
Explanation:
The difference in time will be due to travel through atmosphere where speed of light slows down. If t be the thickness of atmosphere and c be the speed of light in space and μ be the refractive index of atmosphere difference in travel time will be as follows .
difference = \frac{2t\mu }{c}-\frac{2t }{c}
=\frac{2t}{c }\left ( 1-\mu \right )
Now t = 40 x 10³m ,μ = 1.000293 , c = 3 x 10⁸.
difference =\frac{2t\mu }{c}-\frac{2t }{c}
=\frac{2t}{c }\left ( \mu -1 \right )\\
=\frac{ 2\times 40\times 10^3}{3\times10^3 }\left ( 1.000293-1 \right )\\
=7.81\times 10^{-3}

Answer:
When the rocket's engines are fired up, the force of gravity is disturbed, and the rocket takes off in the air. Later, as the rocket's fuel runs out, it slows down, comes to a halt, and eventually plummets to Earth's surface. Forces can affect objects in space as well. Spaceships are constantly in motion while traversing the solar system.

Answer:
The answer should be C
Explanation:
The reason for that is because electromagnet needs electricity to start attracting anything at all but it's attracting power is also stronger because of it
