Yeah i think with a car or a plane:)
Im pretty sure its A cuz is closer to the earth.
The gravitational force between the Earth and the satellite (its "weight") is inversely proportional to the distance between the centers of both objects.
On the surface, their centers are separated by 1 Earth radius.
12,000 miles above the surface, they're separated by 4 Earth radiii.
(4/1) = 4
So after the move, the satellite's weight is (1/4²) = 1/16 of its surface weight.
(321 lb) / (16) = (20 and a hair) lb
The correct choice from the given list is " <em>>20 lb "</em> .
Answer:
The total number of electrons is 
(3) is correct option.
Explanation:
Given that,
The current equation is

We know that,
The formula of charge








We need to calculate the number of electron
Using formula of charge




Hence, The total number of electrons is
