Calculate the capacitance of a system that stores 2.0 x 10^-10c of charge at 100.0 v. use c=q/v. a. 2.0 x 10^-12 f b. 2.0 x 10^-8 f c. 5.0 x 10^11 f d. 5.0 x 10^7 f

2 x 10⁻¹²F

Explanation:

Capacitance is defined as the ration of charge (q) on either plates to the potential difference V between them.

                        C =

Where  q is the charge on the plates

             V is the potential difference

From the given parameters:

Charge on plate, q = 2.0 x 10⁻¹⁰C

Potential difference across the plate = 100V

Unknown parameter:

Capacitance of the system = ? = C

Solution

        Capacitance = 2.0 x 10⁻¹⁰/100 = 2 x 10⁻¹²F

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
