Because its has to use tihs potential energy to overcome the atmosphere so the shuttle will not go back down
Okay, haven't done physics in years, let's see if I remember this.
So Coulomb's Law states that

so if we double the charge on

and double the distance to

we plug these into the equation to find
<span>

</span>
So we see the new force is exactly 1/2 of the old force so your answer should be

if I can remember my physics correctly.
Answer:
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense
Explanation:
Answer:
p=1
Explanation:
Well me know that v=m/s
and that a=m/s^2
so

Note: We don't take into account 2 because it's a scalar, it doesn't have units so it doesn't add anything to the equation.
