Using newton's law of gravity on a 1kg mass near the star. G is newton's grav constant. g is acceleration of grav at starGMstar/r^2 = gstar
Answer: holding the ball in the air without moving it
Explanation:
When the ball goes up it’s potential energy
Answer:
The energy stored in capacitor B is four times the energy stored in capacitor A
Explanation:
First let the write-out the formula for the energy stored in a capacitor in-terms of the capacitance(C)and the voltage(V)
For capacitor A charged to a voltage of V, The energy stored is
and for capacitor B, we have
From the energy stored in Capacitor A we can arrive at
if we substitute this value into the energy for capacitor B we arrive at
Hence we can conclude that the energy stored in capacitor B is four times the energy stored in capacitor A
