Eight equal drops of water are falling through air with a steady velocity of `0.1 ms^(-1)` combine to form a single drop, what should be the new terminal velocity.

Explanation

To solve the problem of finding the new terminal velocity when eight equal drops of water combine to form a single drop, we can follow these steps:

### Step 1: Understand the relationship between volume and radius
The volume of a single drop (V1) can be expressed as:
\[ V_1 = \frac{4}{3} \pi r_1^3 \]
where \( r_1 \) is the radius of one small drop.

When eight drops combine, the total volume (V_total) becomes:
