Topic:

Waves and Oscillations

Question:

Waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave are called?

Options:

  • Traverse waves
  • Electromagnetic waves
  • Compression waves
  • None of the above

Correct Answer:

Compression waves

Explanation:

Longitudinal waves, also known as “l-waves”, are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave. Mechanical longitudinal waves are also called compressional waves or compression waves, because they produce compression and rarefaction when travelling through medium. The other main type of wave is the transverse wave, in which the displacements of the medium are at right angles to the direction of propagation.

Topic:

Alternating Current

Question:

A DC battery can pass current continuously through?

  1. Resistor
  2. Capacitor
  3. Inductor

Options:

  • I only
  • I and II only
  • I and III only
  • I, II and III

Correct Option:

I and III only

Explanation:

DC current cannot flow through a capacitor continuously because of the presence of an insulating medium between the plates of the capacitor.

Topic:

Nuclear physics

Question:

The energy obtained in a nuclear reaction is derived from:

Options:

  • Mass defect and binding energy
  • Fission
  • Fusion
  • All of these

Correct Answer:

All of these

Explanation:

The sum of the individual masses of the parts of a nucleus is less than their mass when they are bound into the nucleus producing mass defect. The mass from the mass defect is converted into the energy that holds the nucleus together and is released in fission. Fusion also produces energy when individual nuclei are forced to combine (fusion) and form new elements in a process that produces energy.
