Where is the pressure greater, one meter beneath the surface of Lake Michigan or one meter beneath the surface of a swimming pond? a. In Lake Michigan b. The pressure is approximately the same in both places c. In the pond
B They both have the same pressure because at the same depth Answer B They both have the same pressure because at the same depth
weight of the fluid displaced b. mass of the fluid displaced c. Archimedes' principle says that an object is buoyed up by a force that is equal to the _____. a. weight of the fluid displaced b. mass of the fluid displaced c. volume of the fluid displaced d. mass of the object e. none of the above
weight of the fluid displaced Answer A weight of the fluid displaced
The reason objects immersed in a fluid experience an upward buoyant force is because fluid pressure on the bottom of the object is greater than fluid pressure on the top of the object. a. True b. False
Answer A True
The reason a life jacket helps you float is that _____. the jacket repels water b. the jacket makes you weigh less c. the jacket has the same density as an average human d. you and the jacket together have density less than your density alone
you and the jacket together have density less than your density alone Answer D you and the jacket together have density less than your density alone
neither float nor sink, but stay anywhere it is put c. float If an object has a density greater than the density of water, it will _____. a. sink b. neither float nor sink, but stay anywhere it is put c. float
Answer A. sink
The reason an iron ship doesn't sink is that _____. iron is less dense than water b. air inside decreases it's weight c. the iron displaces more water than it would if it were in a solid block d. an iron ship will always sink
Answer c. the iron displaces more water than it would if it were in a solid block
