The energy stored in the capacitor decreases to one-half (½) of its initial value when the distance between the plates is then reduced to d/2.
<h3>The energy stored in a capacitor.</h3>
Mathematically, the energy stored in a capacitor can be calculated by using this formula:
U = ½CV² or U = q²/2C
<u>Where:</u>
- V is the potential difference.
Thus, we can logically deduce that the energy stored in the capacitor decreases to one-half (½) of its initial value when the distance between the parallel plate capacitors is reduced to d/2.

Answer:
Thus, any projectile that has an initial vertical velocity of 21.2 m/s and lands 10.0 m below its starting altitude spends 3.79 s in the air.The initial vertical velocity is the vertical component of the initial velocity: v 0 y = v 0 sin θ 0 = ( 30.0 m / s ) sin 45 ° = 21.2 m / s .
