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

Options

A. Reynold Number and coefficient of frication
B. Latent heat and gravitational potentail
C. Curie and frequency of light waver
D. Planck's constant and torque.

Answer

(a,b,c)

Explanation

(a) Reynold number and coefficient of friction, both are dimensionless
(b) `L = (Q)/(m) = (ML^2 T^(-2))/(M) = [L^2 T^(-2)]`
Gravitational Potential `=(W)/(m) = (ML^2 T^(-2))/(M)`
`=[L^2 T^(-2)]`
(c ) `1 curie = 3.7 xx 10^(10) disintergrations// sec `
`=T^(-1)`
Frequency `= T^(-1)`
Choices (a), (b), (c ) are correct.
