Explanation

Full wave rectification is given by four diodes connected in bridge type arrangement.

This configuration allows both halves of the A.C. waveform to be used, producing a smoother and more efficient output compared to half-wave rectification.

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

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

The induced EMF (ε) is given by:

ε = -N(dΦ/dt)

where N is the number of turns, Φ is the magnetic flux, and d/dt is the rate of change of flux.

ε = -600(8-5)/3 = 600V

Explanation

A diode characteristic curve is a plot between voltage and current.

It shows the relationship between the applied voltage across the diode and the resulting current.

It indicating the diode's behavior in both forward and reverse bias.

Explanation

The centripetal force (F) acting on the roller coaster is given by the formula:

F = (m × v^2) / r

Where:

m = net mass of coaster + passengers

v = velocity = 30 m/s

r = radius of the circular track = 30 m

Substituting the values, we get:

F = (m × (30)^2) / 30

= (m × 900) / 30

= 900m / 30

= 900m

So, the centripetal force acting on the roller coaster is 900m.

Explanation

The resistance of a semiconductor with a rise in temperature decreases.

This occurs because increasing temperature provides more energy to charge carriers.

It allowing them to move more freely and conduct electricity better.
