Explanation

Current (I) is defined as the rate of flow of charge (Q) with respect to time (t). The formula to calculate current is:

I = Q / t

Given:

Q = 90 C (charge)

t = 30 s (time)

I = 90 C / 30 s = 3 A

So, the current in the wire is 3 A.

Explanation

The simple machine used in a bicycle to travel is the wheel and axle.

This mechanism allows the wheels to rotate efficiently around the axles.

It enabling the bicycle to move forward with ease.

Explanation

In an intrinsic semiconductor, there are equal numbers of electrons in the conduction band and holes in the valence band

So the Fermi level, which represents the energy level at which the probability of finding an electron is 50%

Lies right in the middle of the band gap between the valence and conduction bands. 

Explanation

In quantum mechanics, the wave function $psi(x, t)$ describes the quantum state of a particle.

The probability density of finding the particle at a particular position in space is given by:

$$P(x) = |psi(x, t)|^2$$

This means:

• The square of the magnitude (or absolute value) of the wave function gives the probability per unit length (or volume) of finding the particle in that region.

• This principle is known as the Born interpretation.

Explanation

The formula to calculate work (W) is:

W = F × d

Where:

F = force (in Newtons)

d = displacement (in meters)

Given:

F = 1 N (force)

d = 1 m (displacement)

W = 1 N × 1 m = 1 J

So, the work done is 1 Joule.

Explanation

An RC low-pass circuit is called a low-pass filter.

It allows signals with frequencies lower than a certain cutoff frequency to pass through while attenuating higher frequencies.
