A generator is a tool that is used in generating electriity. It converts mechanical energy into electrical energy in order to be used in an external circuit. The motors used for the conversion of energy contains a wire coil that is in a magnetic field. This wire coil is being used as a motor or as a generator. Using it as a generator, the wire coil should be spun results to inducing a current in the coil. When a wire coil is being spun in magnetic field, an AC electricity at constant rate is being produced which is then used by an external circuit. Generators are especially important during times of black out and lack of electricity supply from providers.

Answer:

C

Explanation:

Using the two formulas q =CV and C =<em>∈A/d where q = charge, C = Capacitance, V =Voltage, ∈=permittivity of dielectric, A = area of plates and d = distance between plates. </em>Increasing the plate separation decreases the Capacitance thereby decreasing the charge also.

Answer:

Option B

10.36 m/s

Explanation:

Using the first given equation, then velocity=distance/time

Since distance is provided as 200 m and time, t is 19.3 seconds then substituting these figures yields

v=200/19.3=10.3626943

Rounding off to 2 decimal places, then

v=10.36 m/s
