Explanation

Transverse waves involve oscillations perpendicular to the direction of travel and can be polarized, while they do not necessarily require a medium to travel (e.g., light waves).

Explanation

When a sound wave moves from one medium to another, the quantity that remains the same is its frequency. 

The frequency of a sound wave is determined by the source of the sound and doesn't change when it enters a different medium.

However, the wavelength and speed of the wave can change depending on the properties of the new medium. 

Explanation

A centripetal force always acts perpendicular to the direction of an object's motion.

Meaning it doesn't contribute to the object's speed or change in kinetic energy, which is the definition of work. 

Explanation

 When a body moves against the force of friction on a horizontal plane, the work done by the body is negative.

This is because work is defined as the dot product of force and displacement,

And when moving against friction, the force of friction acts in the opposite direction to the displacement of the body,

Resulting in an angle of 180 degrees between them. 

Explanation

Explanation

When two waves of the same frequency and amplitude travel in opposite directions, they superpose to form standing waves.

These waves have nodes (no movement) and antinodes (maximum movement).

Explanation

Explanation

According to Newton's second law, 

F=ma, a constant non-zero force results in uniform acceleration of the mass.

Explanation

Boltzmann's constant (k_B) is a fundamental constant in physics.

The value of Boltzmann's constant is 1.38 × 10^(-23) J/K.

Explanation

The time rate of change of magnetic flux has the same dimensions as that of potential difference (or electromotive force - EMF).
