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

Explanation

In a series RLC circuit, when the value of inductive reactance (XL) is equal to (XC)

it is the condition of series resonance.

Under such conditions, the impedance of the circuit is minimum and equal to the value of resistance (R).

Since the resistance is minimum.

So, the value of the current at resonance is maximum.

Explanation

Electrons typically have greater kinetic energy compared to protons and neutrons because of their significantly lower mass.

Explanation

Stokes' Law holds for objects moving through a viscous medium.

This includes liquids such as water, oil, or molasses, as well as gases such as air, provided that the Reynolds number is sufficiently low for the viscous forces to dominate.

Stokes' Law is a principle that describes the drag force experienced by a small spherical object moving through a viscous fluid.

It specifically applies to objects moving at low Reynolds numbers, where the viscous forces dominate over inertial forces.

Explanation

Indicate high-frequency electromagnetic waves:

Adiabatic Process:

An adiabatic process is one in which there is no heat exchange with the surroundings. When a tire bursts suddenly, the air inside the tire expands rapidly without any heat transfer to or from the surroundings.

This rapid expansion without heat exchange is characteristic of an adiabatic process.

Expansion:

The bursting of the tire leads to a sudden increase in volume, which is an expansion process.

Explanation

if the phase of vibration Θ = π/ z radians, and you are saying that a quarter of the cycle is completed

Then we can equate these two conditions to find the value of z.

In Simple Harmonic Motion (SHM), one complete cycle corresponds to 2π radians. Therefore, if  Θ = π/ z radian represented a quarter of the cycle, then we can write:

 Θ = π/ z = 1/ 4 x 2 π

simplifying 

  π/ z =  π/ 2

 Now, to find the value of z, we can cross-multiply

z = 2

So, when the phase of vibration Θ = π/ z radians and a quarter of the cycle is completed, the value of z is 2.

Explanation

To find the resultant magnitude of two forces acting at right angles (90°), use the Pythagoras' theorem:

Resultant (R) = √(F₁² + F₂²)

Given:  

- F₁ = 6 N  

- F₂ = 8 N  

R = √(6² + 8²) = √(36 + 64) = √100 = 10 N
