Aparallel-plate capacitor in air has a plate separation d = 4 mm and square plates with area a = 25.0 cm^2. the plates are maintained to a constant potential difference of 255 v. determine the charge on the plates and the energy stored by the capacitor.

Explanation:

Given

Separation (d)=4 mm

Area of cross-section

Potential difference=255 V

charge

Energy stored

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
