PHYC lab 8 Archemedes principle
Archimedes' principle compares the relationship between buoyancy and
a. an object
b. buoyant force
c. displaced fluid
d. pressure - correct answer c. displaced fluid
What is the buoyant force that acts on a 2,300,000 N boat if it doesn't sink
a. 230,000 N
b. 234,000 N
c. 2,300,000 N
d. 22,540,000 N - correct answer c. 2,300,000 N
If the weight of an object that is submerged in a fluid is 10 N and the buoyant force on it is 20 N, what will
happen to the object?
a. It will sink
b. It will float
c. It will neither sink nor float
d. more info needed - correct answer b. it will float
If a rock is tossed into a lake, the deeper it sinks, the buoyant force_______
a. increases
