An identical book is dropped on four planets of unknown gravity. The book is thrown down on planets W and X, and released from rest on planets Y and Z. The velocity is recorded for some time intervals on each planet, but not all. The missing velocities are blocked out with a gray box. Which of the following lists the planets in order from the greatest acceleration of gravity to the least acceleration of gravity?

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

elctricity and magnet is conversion to it

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
