Question 1.
Define vorticity.
Show hintHide hint
Think about how we describe rotational characteristics.
Question 2.
What does linear strain refer to?
Show hintHide hint
Consider how fluid elements stretch or compress.
3Question 3.
What is the formula for calculating displacement?
- Displacement = velocity * time
- Displacement = time * acceleration
- Displacement = velocity + time
Show hintHide hint
Think of how distance relates to speed.
4Question 4.
True or False: Vorticity can be zero.
- True
- False
Show hintHide hint
Consider fluid scenarios without rotation.
Question 5.
A fluid particle moves 5 m/s in a straight line for 3 seconds. Calculate the displacement and explain the concept involved.
Show hintHide hint
Use the displacement formula discussed.
Question 6.
In a cyclone, the wind speeds differ significantly between the outer and inner edges. How does this relate to vorticity and fluid characteristics?
Show hintHide hint
Think about the impacts of varying velocities in a confined space.
