Reynold’s number
= Coefficient of friction = [M0L0T0]
Note : Curie is the unit of radioactivity (number of atoms decaying per second) and frequency also has the unit per second.

Dimensions of Physical Quantities:
Reynolds number, coefficient of friction, Curie, frequency of a light wave, latent heat, gravitational potential, Planck's constant, and torque are all physical quantities that have specific dimensions associated with them.
Explanation:
Reynolds Number and Coefficient of Friction:
- Reynolds number is a dimensionless quantity used in fluid mechanics to predict flow patterns in different fluid flow situations.
- Coefficient of friction is a dimensionless quantity that represents the ratio of the force of friction between two bodies to the force pressing them together.
- Since both Reynolds number and coefficient of friction are dimensionless quantities, they have the same dimensions.
Curie and Frequency of a Light Wave:
- Curie is a unit of measurement used in physics to describe the rate of change of an electromagnetic wave's frequency.
- Frequency of a light wave is the number of waves that pass a fixed point in a given time.
- Both Curie and frequency of a light wave have dimensions of inverse time (T^-1), making them quantities with the same dimensions.
Latent Heat and Gravitational Potential:
- Latent heat is the energy absorbed or released during a phase change of a substance at a constant temperature.
- Gravitational potential is the amount of potential energy associated with an object's position in a gravitational field.
- Both latent heat and gravitational potential have dimensions of energy per unit mass, representing quantities with the same dimensions.
Therefore, the pairs of physical quantities that have the same dimensions are Reynolds number and coefficient of friction, Curie and frequency of a light wave, and latent heat and gravitational potential.
