A neutral solution has a pH value of 7, which is neither acidic nor basic.

θ = tan⁻¹(X/R) = tan⁻¹(40/30) = 53.13°.

In simple harmonic motion, acceleration is always opposite to displacement, hence the phase difference is 180 degrees.

In simple harmonic motion, the acceleration is always directed towards the mean position and is 180 degrees out of phase with the displacement.

In simple harmonic motion, acceleration is 180 degrees out of phase with displacement.

At resonance, the phase difference between the driving force and the displacement is 0 degrees.

At resonance, the phase difference is 90°.

At resonance, the phase difference between the driving force and the displacement is 180 degrees.

In a purely resistive circuit, the voltage and current are in phase, so the phase difference is 0°.

At resonance in a series RLC circuit, the phase difference between voltage and current is 0°.

If they have the same frequency and direction, the phase difference is 0.

If two particles are in the same position at the same time in simple harmonic motion, they have a phase difference of 0.

When two particles are in phase, they reach their maximum and minimum displacements at the same time, resulting in a phase difference of 0 radians.

A phase difference of 90 degrees corresponds to π/2 radians.

The phase difference between two points in the same wave separated by a distance of λ/2 is π radians.

The phase difference Δφ between two points separated by a distance of λ/4 is given by Δφ = (2π/λ)(λ/4) = π/2 radians.

The phase difference between two points that are half a wavelength apart is π radians.

The phase difference between two points on a wave that are one wavelength apart is 2π radians.

A phase difference of 180° corresponds to the waves being out of phase, leading to destructive interference.

When two waves are in phase, their phase difference is 0 radians.

Constructive interference occurs when the phase difference is an integer multiple of 2π, which corresponds to a phase difference of 0.

Destructive interference occurs when the phase difference is π radians (or an odd multiple of π).

The S phase (Synthesis phase) is where DNA replication occurs, resulting in the duplication of chromosomes.

The G1 phase is the first stage of interphase where the cell grows and prepares for DNA replication.

The phenomenon of inducing an electric current in a conductor due to a changing magnetic field is known as electromagnetic induction.

The phenomenon is known as electromagnetic induction, as described by Faraday's law.

The phenomenon of inducing an EMF in a conductor due to a changing magnetic field is known as electromagnetic induction.

This phenomenon is known as electromagnetic induction, where a changing magnetic field induces an electric current in a conductor.
