The surface tension of a soap solution is `30 xx 10^(-3) N m^(-1)`. How much work is done to increase the radius of a soap bubble from 2 cm to 3 cm?

Explanation

To solve the problem of how much work is done to increase the radius of a soap bubble from 2 cm to 3 cm, we can follow these steps:

### Step 1: Understand the Concept of Work Done on a Soap Bubble
The work done on the soap bubble is related to the change in surface area of the bubble. Since a soap bubble has two surfaces (inner and outer), we need to account for this when calculating the work done.

### Step 2: Formula for Work Done
The work done (W) to change the surface area of the soap bubble can be expressed as:
\[ W = T \cdot \Delta A \]
