What are dimensions of Planck's constant. What other physical quantity has the same dimensions ?

Explanation

To find the dimensions of Planck's constant and identify another physical quantity with the same dimensions, we can follow these steps:

### Step 1: Identify the unit of Planck's constant
Planck's constant (h) is defined in terms of its units, which are:
\[ \text{Unit of Planck's constant} = \text{kg} \cdot \text{m}^2 \cdot \text{s}^{-1} \]

### Step 2: Write down the dimensions of Planck's constant
The dimensions of Planck's constant can be expressed in terms of fundamental quantities:
