General Physics Ques 18
The pairs of physical quantities that have the same dimensions are (are )
$(1995,2 M)$
(a) Reynolds number and coefficient of friction
(b) Curie and frequency of a light wave
(c) latent heat and gravitational potential
(d) Planck’s constant and torque
Show Answer
Answer:
Correct Answer: 18.( a, b, c )
Solution:
- Reynold’s number and coefficient of friction are dimensionless quantities. Curie is the number of atoms decaying per unit time and frequency is the number of oscillations per unit time. Latent heat and gravitational potential both have the same dimension corresponding to energy per unit mass.
