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

Step 1: Analyze Pair (1) — Reynolds number and coefficient of friction.

The Reynolds number $\text{Re}$ is defined as:

$$\text{Re} = \frac{\rho v D}{\mu}$$

Since all units cancel out, it is dimensionless:

$$[\text{Re}] = M^{0}L^{0}T^{0}$$

The coefficient of friction $\mu_{\text{fr}}$ is the ratio of two forces:

$$\mu_{\text{fr}} = \frac{F_{\text{fr}}}{N}$$ $$[\mu_{\text{fr}}] = M^{0}L^{0}T^{0}$$

Both quantities are dimensionless, so they have the same dimensions.

Step 2: Analyze Pair (2) — Curie and frequency of a light wave.

Curie is a unit of radioactivity representing decay rate per unit time:

$$\text{Curie} = \frac{\Delta N}{\Delta t}$$ $$[\text{Curie}] = T^{-1}$$

The frequency $\nu$ of a light wave is:

$$\nu = \frac{1}{T}$$ $$[\nu] = T^{-1}$$

Both quantities have the same dimension of inverse time.

Step 3: Analyze Pair (3) — Latent heat and gravitational potential.

Latent heat $L$ is heat energy per unit mass:

$$L = \frac{Q}{m}$$ $$[L] = \frac{ML^{2}T^{-2}}{M} = M^{0}L^{2}T^{-2}$$

Gravitational potential $V$ is work done per unit mass:

$$V = -\frac{GM}{r}$$ $$[V] = M^{0}L^{2}T^{-2}$$

Both quantities have the same dimensions.

Step 4: Analyze Pair (4) — Planck's constant and torque.

Planck's constant $h$ is defined via energy and frequency:

$$h = \frac{E}{\nu}$$ $$[h] = \frac{ML^{2}T^{-2}}{T^{-1}} = ML^{2}T^{-1}$$

Torque $\tau$ is defined as force times perpendicular distance:

$$\tau = F \times r$$ $$[\tau] = ML^{2}T^{-2}$$

These two quantities have different dimensions.

Answer: The pairs of physical quantities that have the same dimensions are (1) Reynolds number and coefficient of friction, (2) Curie and frequency of a light wave, and (3) Latent heat and gravitational potential.
