Show hintHide hint
Think about what pressure means when the fluid is moving.
Question 2.
Define superposition in the context of waves.
Show hintHide hint
Consider how waves behave while overlapping.
3Question 3.
What defines dynamic pressure in fluid mechanics?
- Pressure when fluid is still
- Pressure exerted by fluid motion
