PLEASE HELP The mass of the earth is 81 times the mass of the moon. Using Newton's Law of Gravity what would the affect of gravitation be if the mass of the moon were
doubled and the distance was also doubled?

a. twice the gravitational attraction

b. 4 times the gravitational attraction

c. half the gravitational attraction

d. 1/4 the gravitational attraction

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
