Show hintHide hint
Think about how mass behaves in an isolated system.
Question 2.
What are body forces?
Show hintHide hint
Consider forces like gravity.
3Question 3.
What does the conservation of mass state?
- Mass can be created
- Mass is constant
- Mass can be destroyed
Show hintHide hint
Consider what happens in a closed environment.
4Question 4.
True or False: Surface forces are primarily caused by gravitational effects.
- True
- False
Show hintHide hint
Remember the definition of surface forces!
Question 5.
A closed tank filled with fluid has a mass of 1500 kg. If 300 kg is added and no fluid is lost, calculate its final mass.
Show hintHide hint
Apply the conservation of mass principle.
Question 6.
Two fluids of different densities are mixed in a container. If the total mass is 5 kg and the volume stays the same, how do the densities relate?
Show hintHide hint
Consider mass conservation while calculating density!
