- 1. Multiple Choice
How do we calculate density? (with correct units!)D = m/v (in g/mL or g/cm3)D = v/m (in g/mL or g/cm2)D=m/v (in mL/g or cm3/g) - 2. Multiple Choice
Buoyancy is the tendency for objects to float in a fluid. We consider buoyancy the...
Un-gravity force
The upward force
Gravitational pull
Downwards pull on an object
- 3. Multiple ChoicePressure at the bottom of the ocean is greatest because:The water is most dense at the bottom.The water is least dense at the bottom.The water is buoyant at the bottom.
- 4. Multiple ChoiceIf the mass of an object is greater than the buoyant force, the object will:FloatSink
- 5. Multiple ChoiceWhen you hold an object in the water,Water is displaced and risesWater is displaced and decreasesThe buoyant force pushes down on the object
- 6. Multiple Choice
When you increase your depth under water, the water pressure on your body
increases
decreases
stays the same
- 7. Multiple ChoiceDensity is defined as...Centimeters cubed per mass of substanceMass per unit volume of a substanceFlow rate of a substance
- 8. Multiple ChoiceArchimedes' Principle states that...The buoyant force acting on an object equals the volume of the fluid displaced by the object.The buoyant force acting on an object equals the weight (force of gravity) of the fluid displaced by the object.The buoyant force acting on an object will always be equal.
