Become more positive instead of negative
Answer:
Explanation:
for the calculation of the electric potential inside a parallel plate capacitor you can use the formula for the electric field inside the capacitor.
where d is the distance between plates and E is the electric field, which is given by:
By replacing you obtain:
where Q is the charge stored by the capacitor and A is the area of the plates.
hence, the answer is Qd/Ae0
The properties of the wave don't determine its speed. The properties of the medium do. You can FIND the speed by measuring the wave's frequency and wavelength.
