A5.00 kg mass feels a gravitational
force of 3.07 x 10-8 n from a 7.50
kg mass. how far are they apart?

Both masses are 0.285 m apart

Explanation:

According to the law of Universal Gravitation:

Where:

is the gravitational force between the masses

is the gravitational constant

 is the mass of the first object

  is the mass of the second object

is the distance between the objects

Isolating :

This is the distance between both objects

radiation

explanation:

heat is transmitted by radiation

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
