Options A, B, and C do not contain alpha particles, which have the strongest ionizing power. Option D is therefore appropriate.

A coil or loop that carries current functions similarly to an electromagnet. The clock face rule can be used to understand this magnet’s polarity. That face of the loop displays the North Pole if the current is flowing counter-clockwise. In contrast, that face of the loop displays the South Pole if the current is flowing clockwise.

Current times voltage equals power.

1.5 x 220

P is equal to 330 watts.

Balmer, Paschen, Brackett, Pfund, and Lyman are the five spectral series. The electron returns to n = 1 in the Lyman series. The obtained spectral lines fall within the electromagnetic spectrum’s ultraviolet region. The electron returns to n = 2 in the Balmer series, and the resulting spectral lines fall within the visible portion of the electromagnetic spectrum. The infrared portion of the electromagnetic spectrum yields the Paschen, Brackett, and Pfund spectral lines.

When a machine’s parts rotate, friction losses occur.

There is no frictional loss in a transformer regardless of the loading condition because it is a static device, meaning it has no moving parts of any kind.

Therefore, choice D is the right one.

The quantity of radioactive samples decreases by half with each half-life.

Life in the First Half: 400->200

Life in the second half: 200 to 100

Life in the third half: 100->50.

The area where the magnetic field is present or distributed is called the flux. The magnetic field flowing through a particular region or surface is referred to as the flux in the context of this question. Within the area, the magnetic field lines may vary in strength and direction, but they are always connected by a polarity. The magnetic field lines’ orientation or direction—whether north or south—is indicated by their polarity.
