Formulas
What is the formula for density?
P=m/v
What does incompressible mean?
Not able to be compressed (pushed together).
A valuable statuette from a Greek shipwreck lies at the bottom of the Mediterranean Sea. The statuette has a mass of 10,566 g and a volume of 4,064 cm3. The density of seawater is 1.03 g/mL.
What is the weight of the statuette?
103.76N
A solid is a fluid.
False
What are the properties of an ideal fluid?
Incompressible and has no internal friction
LxWxH
What is the definition of density?
Mass per unit of volume
A valuable statuette from a Greek shipwreck lies at the bottom of the Mediterranean Sea. The statuette has a mass of 10,566 g and a volume of 4,064 cm3. The density of seawater is 1.03 g/mL.
What is the mass of the displaced water?
4185.92g
Immersed can mean either partly submerged or totally submerged
True
A submerged object will experience a bouyant force equal to the weight of a displaced fluid.
What is the equation for pressure?
P = D x G x H
What is a fluid?
Any substance that alters its shape because its particles can move around
A valuable statuette from a Greek shipwreck lies at the bottom of the Mediterranean Sea. The statuette has a mass of 10,566 g and a volume of 4,064 cm3. The density of seawater is 1.03 g/mL.
What is the weight of the displaced water?
41.11N
Air pressure is the weight of air molecules pushing down on Earth.
True
What is Bernoulli’s principle?
As the air moves around an object, it creates different pressures on that object
What is the formula for Boyle’s Law?
PV=K
What is the definition of air pressure?
The weight of air molecules pushing down on Earth.
A valuable statuette from a Greek shipwreck lies at the bottom of the Mediterranean Sea. The statuette has a mass of 10,566 g and a volume of 4,064 cm3. The density of seawater is 1.03 g/mL.
What is the buoyant force on the statuette?
41.11N
Particles of a fluid do not exert pressure on one another.
False
What is Pascal’s theorem for an enclosed fluid at rest?
Any change in pressure at any point in the fluid is transmitted undiminished to all points in the fluid and acts in all directions
What is the equation for Bernoulli’s principle?
P = PxGxH
What is buoyancy?
Upward force exerted by a fluid.
A valuable statuette from a Greek shipwreck lies at the bottom of the Mediterranean Sea. The statuette has a mass of 10,566 g and a volume of 4,064 cm3. The density of seawater is 1.03 g/mL.
What is the net force on the statuette?
-62.65 N
Atmospheric pressure at sea level is 14.6 psi
False (14.7 psi)
What is Pascal’s Law?
Pressure applied on one point of a liquid transmits equally in all directions.
