b

MCQ 5:

**Bernoulli's principle shows that, at points in a moving fluid where the potential energy change is very small**

- the pressure is low where the velocity is low and similarly, the pressure is high where the velocity is high
- the pressure is low where the velocity is high and conversely, the pressure is high where the velocity is low
- pressure becomes independent of the velocity of the moving fluid
- pressure remain independent of the speed of the stationary fluid
