The magnitude and direction of the current in the following circuit is:

An AC source is connected to a capacitor $C$. Due to a decrease in its operating frequency:

The net magnetic flux through any closed surface is:

In a plane electromagnetic wave travelling in free space, the electric field component oscillates sinusoidally at a frequency of $2.0\times 10^{10}\text{Hz}$ and amplitude $48{\text{V m}}^{-1}$. Then the amplitude of the oscillating magnetic field is (Speed of light in free space $=3\times 10^8{\text{m s}}^{-1}$):

The potential energy of a long spring when stretched by $2\text{cm}$ is $U$. If the spring is stretched by $8\text{cm}$, the potential energy stored in it will be:
