Equilibrium is a state of no motion. If donuts are on the table, they are in equilibrium. Literally anything that is NOT moving relative to the earth is in equilibrium. The chair is in equilibrium, the table is in equilibrium, the cookies are in equilibrium, and so on.
Answer: That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity. Newton was the first to theorize that a projectile launched with sufficient speed would actually orbit the earth.
Explanation: Because Earth-orbiting objects follow elliptical paths around Earth and not a straight line, forces cannot, by definition, be balanced. Force is directional. It is a push or a pull in a particular direction.
Answer:
the answer is d
Explanation:
from F=Q1Q2
r².
then wen both charges are doubled
F=2Q1 ×2Q2
r²
F=4Q1Q2
r²
then 4 has to be the factor multiplied by the other part of the equation for it to balance
4F=4Q1Q2
r²
so theoretically the 4 on the LHS can cancel the 4 on the RHS
