Explanation

The current produced by induced EMF depends on :

• Area of the coil
• Turns of the coil
• Strength of the magnetic field in which the coil rotates

Explanation

If two streams of protons move parallel to each other in the same direction, they repel each other. 

Protons are positively charged particles, and according to Coulomb's law, particles with the same charge repel each other.

This repulsive electrostatic force dominates between the protons, causing them to push away from each other. 

Explanation

To obtain greater dispersion by a diffraction grating, the slit separation should be decreased. 

Dispersion:

• In diffraction gratings, dispersion is the separation of light wavelengths during diffraction, with greater dispersion resulting in wider color separation.

Slit separation:

• The distance between individual slits on the grating is called the slit separation.

Relationship between slit separation and dispersion:

• Smaller slit separations lead to larger angles of diffraction for a given wavelength, resulting in greater dispersion.
• Imagine the light waves as being "bent" more by the closer slits, causing them to spread out further

Explanation

Sound waves diffract (bend) around corners, allowing us to hear them,

While light waves do not diffract as much, making it impossible to see around corners.

Diffraction is the bending of waves around obstacles or through openings.

Sound waves have longer wavelengths than light waves, which makes diffraction more noticeable for sound.

Polarization is a property of transverse waves, and while light waves can be polarized, sound waves cannot.

Dispersion is the separation of waves into different frequencies,

And while it can occur with light, it's not why we can hear around corners. 

Explanation

The principle of conservation of linear momentum is a direct consequence of Newton's Third Law of Motion.

While Newton's Second Law relates force to the rate of change of momentum (F = dp/dt),

It's the reciprocal action-reaction nature described in the Third Law that leads to the preservation of total momentum in an isolated system. 

Explanation

The core principle behind a hydrogen bomb is the fusion of light atomic nuclei.

Specifically isotopes of hydrogen (deuterium and tritium), under extremely high temperatures and pressures. 

Explanation

Explanation

If the speed of a moving particle increases, the wavelength associated with it will decrease. 

This is due to the relationship between wavelength and momentum in the de Broglie equation, where wavelength is inversely proportional to velocity. 

Explanation

The statement "The mechanical energy spent by the external agency is converted into electrical energy stored in the coil" relates to Lenz's law. 

Explanation

• One parallel to the field (causes straight motion)
• One perpendicular to the field (causes circular motion)
