The pairs of physical quantities that have the same dimensions is (are)

Options

A. Reyond number and coefficient of light wave
B. Curie and frequency of light wave
C. Latent heat and gravitational potential
D. Planck's constant and torque

Answer

A, B, C

Explanation

(a) . Reynold number and coefficient of friction of both are dimensionless.
(b). Curie has unit disintegrations / second. Curie and frequency both have dimensions `[T^(-1)]`.
( c ) Latent heat `= ("Heat energy")/("Mass")`
Gravitational potential `= ("Gravitational energy")/("Mass")`.
Both have dimensions `[L^(2) T^(-2)]`.
Planck's constant has dimensions `[ML^(2) T^(-1)]` whereas torque has dimensions `[ML^(2) T^(-2)]`.
