Therefore, the capacity of a parallel plate capacitor directly depends on the relative permittivity of dielectric material, the permittivity of space, the area of plates, and is inversely dependent on the separation between the plates.

1. Induced current is highest when the direction of motion of the coil is perpendicular to the magnetic field.

Its molecular mass will be: 64u.

The damping force of an oscillating particle is observed to be proportional to velocity. The constant of proportionality can be measured in. kgs−1.

The Doppler effect was discovered by Austrian scientist Christian Doppler in 1842, describing the change in frequency of any type of sound or light wave produced by a moving source with respect to an observer.

1. The device which is used to measure electric current in an electric circuit is called ammeter.

2. The resistance of an ideal ammeter is always zero and the electric circuit is always connected in series.
