Explanation

The component of electronics that acts as a rectifier is a diode.

Diodes allow current to flow in one direction only.

It enabling the conversion of alternating current (A.C.) into direct current (D.C.) by blocking the reverse flow.

Explanation

A causal system depends on present and past input values.

It does not rely on future input values.

This making it practical for real-time processing.

Explanation

Dr. Abdus Salam made significant contributions to the development of quantum electrodynamics and quantum field theory.

His work laid the foundation for the electroweak unification theory, for which he was awarded the Nobel Prize in Physics in 1979.

Explanation

The magnification of a compound microscope is determined by the product of the magnification of the objective lens and the magnification of the eyepiece.

Explanation

In an oscillating LC circuit, the maximum energy stored in the capacitor during one cycle is equal to the total stored energy (U) in the circuit.

This is because the total energy oscillates between the capacitor and the inductor, with the total energy remaining constant in an ideal, lossless LC circuit.

Explanation

When a rotating body decelerates uniformly from an initial angular velocity (ω₀) to zero, the average angular velocity is ω₀/2.

Since the disc was initially rotating at 1 revolution per second, the initial angular velocity (ω₀) is 1 rev/s.

The total number of revolutions (n) is given by:

n = (ω₀/2) * t

where t is the time taken to come to rest.

Since the deceleration is uniform, the time taken to come to rest is:

t = ω₀ / α

where α is the angular deceleration.

Substituting this value of t in the equation for n, we get:

n = (ω₀/2) * (ω₀ / α)

= (1/2) * (1)

= 1

Explanation

The centripetal acceleration of an object moving along a circle of radius 𝑟 with an angular speed 𝜔 is given by the formula 𝑎 = 𝑟 ⋅ 𝜔^2.

This formula indicates that the centripetal acceleration is directly proportional to the radius and the square of the angular speed.
