if we calculate that the total energy of a rollercoaster cart is 500 J at the beginning of the first hill, what is the energy at the top of the hill?

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

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

inverse v=i*r
