A AND B = 0 AND 1 = 0. Therefore, NOT (0) = 1.

Path difference = d sin θ = d sin(45°) = d(√2/2). For d = λ, path difference = √2λ.

Path difference = d sin θ = 1 m * sin(45°) = 1 m * √2/2 = 0.707 m.

The path difference for the first minimum is λ/2, which leads to destructive interference.

The period T of a simple pendulum is given by T = 2π√(L/g). For L = 1 m and g ≈ 9.8 m/s², T = 2π√(1/9.8) ≈ 2 s.

The period of a satellite in a circular orbit at a height of 300 km is approximately 90 minutes.

Satellites in low Earth orbit have a much shorter orbital period compared to geostationary satellites due to their proximity to Earth.

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 180 degrees.

At resonance, the phase difference is 90°.

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

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

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

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.

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

The phenomenon of inducing an EMF 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.

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

When an electron transitions from a higher energy level to a lower energy level, it releases energy in the form of a photon, a process known as emission.

The emission of electrons from a metal surface when exposed to light is known as the photoelectric effect.
