Answer:
Potential
Explanation:
This is because it has not yet fallen, and it has the potential to fall and turn into kinetic energy. When it starts falling, it will be kinetic.
Answer:
First we have to find how many seconds are there in a day which is 86,400 then multiply 86,400 and 4 which equals 345,600
hope this helps
have a great day!

Answer:
the energy comes from the increase in the electric field
Explanation:
The capacitance is
C = ε₀ A / d
The electric charge on the condenser plates
Q = C ΔV
The stored electrical energy is
U = ½ C ΔV²
ΔV = E d
U = ½ (ε₀ A / d) (E d)²
U = ½ ε₀ A d E²
We see that the stored energy is proportional to the square of the electric field, so the capacitor can increase its energy with increasing voltage
In short, the energy comes from the increase in the electric field
