A water pipe is pointed straight up and water flows out from it with constant volume flow rate, reaching a certain maximum height. In order to make the water reach double the height, which of the following adjustments to the nozzle of the pipe will be required?
(a) Decrease the area by a factor of 2
(b) Decrease the area by a factor of `sqrt2`
(c) Decrease the area by a factor of 4.

Explanation

To solve the problem of how to adjust the nozzle of a water pipe to make the water reach double the height, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**:
We have a water pipe that is pointed straight up, and water flows out with a constant volume flow rate (Q). We need to determine how to adjust the nozzle to make the water reach double the height.

2. **Define the Variables**:
