MCQ
The pair(s) of physical quantities that have the same dimensions, is (are)
  • A
    Reynolds number and coefficient of friction
  • B
    Latent heat and gravitational potential
  • C
    Curie and frequency of a light wave
  • All of these

Answer

Correct option: D.
All of these
d
(d) Reynolds number and coefficient of friction are dimensionless.

Latent heat and gravitational potential both have dimension $[{L^2}{T^{ - 2}}]$. 

Curie and frequency of a light wave both have dimension $[{T^{ - 1}}]$. But dimensions of Planck's constant is $[{T^{ - 1}}]$ and torque is $[M{L^2}{T^{ - 2}}]$.

A tuning fork is used to produce resonance in a glass tube. The length of the air column in this tube can be adjusted by a variable piston. At room temperature of $27\,^o C$ two successive resonances are produced at $20\, cm$ and $73\, cm$ of column length. If the frequency of the tuning fork is $320\, Hz,$ the velocity of sound in air at $27\,^o C$ is .... $m/s$
