What are the parts of an atom?
Proton positive charge in the nucleus of an atom. Atomic # (Z) = # of protons determines element
Neutron neutral particle in the nucleus of an atom. Neutron # (N) = # of neutrons determines isotope

What are the 4 states (phases) of matter ? Solid Rigid; retain their shape unless distorted by a force.
Liquid flows readily; conform to the shape of a container; fixed volume
Gas flows readily; conform to the shape of a container; no fixed volume
Plasma superheated ionized gas

Density Weight = DW = Weight/V
Density $300
Answer
Back to Jeopardy
What are the units of density?SI 1 kg/m³ cgs 1 g/cm³ = g/ml common 1 slug/ft³ or Weight density in lbs/ ft³
1 kg/m³ = 0.001 g/cm³ = 2.42 slug/ft³
Density $400

What is the density of water?
DWATER = 1000 kg/m³ = 1 g/ml = 62.4 lbs/ft³
Fluid Equations $100
Answer
Back to Jeopardy
What is the law of fluid pressure?
The pressure at any point in a fluid is determined by the weight of the fluid above. P = Dgh
Fluid Equations $200
Answer
Back to Jeopardy
What is the equation of continuity?
Flow rate = R = Volume/time = constant R = A1*v1 = A2*v2
Fluid Equations $300
Answer
Back to Jeopardy
What is Bernoulli’s Principle?
P1 + Dv1²/2 + Dgy1 = P2 + Dv2²/2 + Dgy2
Fluid Equations $400
Answer
Back to Jeopardy
What is Pascal’s Principle? Any additional pressure in a fluid is passed on uniformly throughout the fluid.
P = F1/A1 = F2/A2
Buoyancy $100
Answer
Back to Jeopardy
If an object is submerged, it will displace its VOLUME in fluid.
Buoyancy $200
Answer
Back to Jeopardy
What is specific gravity?
SG = Density pf object/Density of water
If an object sinks, SG > 1If an object floats. SG < 1
Buoyancy $300
Answer
Back to Jeopardy
What is Archimedes Principle (Buoyancy force)?The upward buoyancy force on an object partly or completely immersed in a fluid is equal to the weight of the fluid displaced.
B = mg FLUID = DFLUID gV

Back to Jeopardy
A hollow sphere has an average density of 3 g/cm3 and a mass of 15 g. 1 mN =.001 N
What will the sphere weigh under water?
a. 45 mN b. 98 mN c. 85 mN d. 80 mN
Volume = 15g/(3 g/cm3 ) = 5 cm³
Weight of object = mg = 147 mN
Weight of water = mWg = 49 mN
Total Weight in water = 98 mN
