The equation of simple harmonic motion is given by:
The general equation for Simple Harmonic Motion (SHM) is: x = A cos(ωt + ϕ) where: - A is the amplitude, - ω is the angular frequency, - t is the time, - ϕ is the phase constant. This describes the displacement x in terms of time, which denotes oscillatory motion. Click here for more: https://www.tiRead more

Which of the following is an example of simple harmonic motion (SHM)?
In Simple Harmonic Motion (SHM), the restoring force is proportional to the displacement and acts in the opposite direction. A pendulum oscillating with a small amplitude follows this condition, where the restoring force is given by: F = -mg sin(θ) ≈ -mgθ (for small angles, sin(θ) ≈ θ) This makes thRead more
In Simple Harmonic Motion (SHM), the restoring force is proportional to the displacement and acts in the opposite direction. A pendulum oscillating with a small amplitude follows this condition, where the restoring force is given by:
F = -mg sin(θ) ≈ -mgθ (for small angles, sin(θ) ≈ θ)
This makes the motion approximately simple harmonic.

The mean free path of a gas molecule is defined as:
The mean free path (λ) of a gas molecule is the average distance traveled by a molecule between two successive collisions. It is defined by: λ = (k_B T) / (√2 π d² P) where: - k_B is Boltzmann's constant, - T is the temperature, - d is the diameter of the molecule, - P is the pressure. Thus, the meaRead more
The mean free path (λ) of a gas molecule is the average distance traveled by a molecule between two successive collisions. It is defined by:
λ = (k_B T) / (√2 π d² P)
where:
– k_B is Boltzmann’s constant,
– T is the temperature,
– d is the diameter of the molecule,
– P is the pressure.
Thus, the mean free path is the average distance traveled before a collision takes place.

A key of a mechanical piano is struck gently and then struck again but much harder this time. In the second case
(a) Sound will be louder but pitch will not be different. When struck harder, amplitude of vibrations will be more and consequently a louder sound is produced. https://www.tiwariacademy.com/ncert-solutions/class-9/science/chapter-11/

See lessThe distribution of molecular speeds in a gas at a given temperature is described by:
The Maxwell-Boltzmann distribution gives the statistical distribution of molecular speeds in a gas at a given temperature. It is defined as: f(v) = (m / 2πk_B T)^(3/2) * 4πv² * exp(-mv² / 2k_B T) where: - m is the mass of a gas molecule, - k_B is Boltzmann's constant, - T is the temperature, - v isRead more
The Maxwell-Boltzmann distribution gives the statistical distribution of molecular speeds in a gas at a given temperature. It is defined as:
f(v) = (m / 2πk_B T)^(3/2) * 4πv² * exp(-mv² / 2k_B T)
where:
– m is the mass of a gas molecule,
– k_B is Boltzmann’s constant,
– T is the temperature,
– v is the molecular speed.
This distribution shows that most molecules have speeds around a certain value, but some move much slower or much faster.
