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)]`.
