Explanation

If an electron has zero orbital angular momentum, its magnetic dipole moment also equals zero

This is because the magnetic dipole moment is directly proportional to the orbital angular momentum, and when the angular momentum is zero, the magnetic moment is also zero.

Explanation

In an ideal transformer, power input is equal to power output.

This is based on the principle of conservation of energy.

It means that the transformer is assumed to have no losses; therefore, the input power (from the primary coil) equals the output power (to the secondary coil).

Explanation

Explanation

The incorrect statement is "Magnetic field is strongest when the lines are farthest."

In fact, the magnetic field is strongest where the lines are closest together.

It indicating a higher density of magnetic field lines.

Explanation

Power is calculated using P = V × I.

Here, I = 51.2 mA = 0.0512 A, so P = 220 V × 0.0512 A = 11.26 W.

Explanation

Light glare can be reduced by the process of polarization.

Polarization is a process that involves filtering out light waves that are oscillating in certain directions.

Glare occurs when light waves from a source, such as the sun or a bright artificial light, are scattered in various directions, leading to a harsh and uncomfortable brightness.

Explanation

Humidity is a key factor in determining the hottest temperature the human body can tolerate.

Humidity affects how well the body can cool itself through sweat evaporation.

Explanation

Gravitational force is responsible for the falling of an apple from a tree

As it is the natural force of attraction that pulls objects toward the Earth.

This force acts between all masses. 

It is what causes objects to fall when unsupported.
