An object falls from a position of rest and reaches an instantaneous speed of 9 m/s.
How far will it have dropped? The acceler-
ation of gravity is 9.8 m/s?.
Answer in units of m.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

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
