Explanation

• Kinetic energy is the energy of motion.
• It is the energy an object possesses when it is in motion, such as a rolling ball, a moving car, or a flying bird.
• The amount of kinetic energy an object has depends on its mass and velocity.

Explanation

• Thermal energy is the form of energy that is transferred from one body to another due to a difference in temperature, and is received from heat.
• It is the energy of motion of particles in a substance, such as atoms or molecules, and is often referred to as "heat energy".

Explanation

The central layer is made very thin and lightly doped as compared with the two outer layers and is called the base.

The outer sections are called emitter and collector.

Explanation

A black body is both an ideal absorber and an ideal radiator of radiation.

It absorbs all incident radiation perfectly and emits radiation at the maximum possible rate for any given temperature.

Explanation

Bulk modulus of elasticity is defined as ratio of hydraulic stress to the corresponding the volumetric strain within the elastic limit.

Bulk modulus K=FVAΔV=Δp⋅VΔV.

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

The current produced in a coil due to electromagnetic induction is called an induced current.

The induced current can be positive or negative depending on the direction of the change in magnetic flux and the orientation of the coil

However, the term "induced current" is used to refer to the current that flows

As a result of electromagnetic induction, regardless of its direction being positive or negative

Explanation

Bremsstrahlung or braking radiation is an example of a continuous spectrum.

The spectrum of Bremsstrahlung radiation is continuous

Because the energy of the emitted photons can vary continuously depending on the degree of deceleration of the charged particles.

This leads to a continuous range of wavelengths or frequencies in the emitted radiation, forming a continuous spectrum.

Bremsstrahlung radiation is commonly encountered in X-ray tubes

Where high-energy electrons are decelerated by a target material

Producing X-rays with a continuous spectrum of energies

Explanation

Compression is a region in longitudinal waves that occurs in high pressure and rarefaction is also a region in longitudinal waves

That occurs where there is extra space or where particles are far away from each other

Both waves are longitudinal waves of sound waves

Explanation

The brightness of the waveform on the screen of a Cathode Ray Oscilloscope (CRO) is primarily controlled by the potential of the cathode.

Here's why:

• Cathode Ray Tube (CRT)
• Electron Beam Intensity
• Potential of the Cathode
