Show hintHide hint
Think about how weight plays a role.
Question 2.
Define buoyancy in a single sentence.
Show hintHide hint
It's related to floating in water.
3Question 3.
What is the pressure exerted by a fluid dependent on?
- Area only
- Weight of the fluid
- Both Area and Weight
Show hintHide hint
Consider both the definitions of pressure and fluid.
4Question 4.
True or False: Objects less dense than water will always sink.
- True
- False
Show hintHide hint
Remember the concept of density and buoyancy.
Question 5.
A diver is testing if a new suit will allow him to float better. The suit has a mass of 5 kg and decreases his density from 1.05 g/cm³ to 0.95 g/cm³ when he wears it. Will the diver float more easily with the new suit? Why or why not?
Show hintHide hint
Consider the relationship between an object's density and the fluid's density.
Question 6.
Calculate the volume of water displaced when a 10 kg object is immersed in a fluid of density 1.2 g/cm³.
Show hintHide hint
Use the formula that connects mass, density, and volume.
