Relationship of static friction and sliding object base area
Independent. There is none.
Relationship of kinetic friction and speed over time. (tension and friction forces are constant)
The coefficient of kinetic friction is always lower than that of static friction. Therefore there is a net accelerating force on the block once it starts to slide making speed increase linearly with time.
What accounts for N2's boiling point being lower than O2's?
N2 has a lower molecular weight than does O2.

Pressure in a liquid is proportional to...
Liquid density and depth
The pH at the equivalence point of a titration is equal to...

Equivalent mass (equivalent weight)
The mass of an acid that yields one mole of hydrogen ions.
The mass of a base that reacts with one mole of hydrogen ions.
Calculating mole fraction
The mole fraction is the number of moles of chemical in question divided by the total number of moles for all other species in solution.
mf of A =
Divide the total pressure by number of molecules (including coefficients).
CH4 + 2O2 CO2 + 2H2O
(maybe products only?)
Empirical formula from grams.
Figure out number of moles. Number of moles equals subscript unless it can be reduced. (e.g. 2:4:2 = 1:2:1)
Open pipe wavelength is 2 times the length of the pipe.
Pipe diameter doesn't matter.
(Photoelectric effect) When the number of photons increases...
The number of electrons ejected increases.
Electron energy is based on the energy of the photon.
Calculating power dissipated as heat in a resistor
The square of the current (I) times the resistance (R).

Increases the speed of the ejected electron.
Fusion (phase changes) definition
Plane mirror characteristic
Produces an image behind its plane at a distance equal to the distance of the object being reflected.

The autonomic nerve fibers that directly innervate the heart to cause cardiac slowing are:
Parasympathetic motor fibers
Amine vs. Amide
Stimulates gluconeogenisis and release of glucose into the blood.
Effect of an impurity on melting points
Slightly lowers and broadens the temperature range of melting.
Relationship between the colon and the appendix
They are connected in such a way that contents may move freely between them.
