HURRY If all else stays the same, which change could be made to cause an increase in the gravitational force on a space shuttle?

1. increasing the distance of the space shuttle from Earth
2. decreasing the distance of the space shuttle from Earth
3. increasing the universal gravitational constant acting on the space shuttle
4. decreasing the universal gravitational constant acting on the space shuttle

2. decreasing the distance of the space shuttle from Earth

Explanation:

To increase the gravitational force on a space shuttle, it is a good thing to decrease the distance of the space shuttle from the earth.

This is based on the Newton's law of universal gravitation which states that "the gravitational force between two bodies is a directly proportional to the product of their masses and inversely proportional to the square of the distance between them".

 Mathematically;

           F  =  

G is the universal gravitation constant, it cannot be changed

m is the mass of the body

r is the distance

  Since the distance is inversely proportional, is we reduce it, the value of the gravitational force will increase.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
