What is the formula for the maximum Force of static friction (Fs)max?
(Fs)max = μsN OR. (Fs)max =
s mg cos 𝜃 (inclined plane)
where μs = coefficient of static friction
N = normal force

Work formula for expansion or compression of a gas (Hint: it relates pressure and volume)
W = -PΔV
300
give the projectile motion formula for final velocity (not final velocity squared)
Vf = V0 +at

Entropy increases, decreases, or is unaffected when a compound undergoes a phase change from a gas to a solid? What is the corresponding sign of ΔS?
When a gas turns into a solid, entropy decreases (because solids are more ordered).
A decrease in entropy corresponds to a negative ΔS
300
What is a Nucleosome?
A nucleosome is a structural unit of a eukaryotic chromosome, consisting of a segment of DNA coiled around 8 histone protein cores.

What is an absolute threshold?
The minimum stimulus required to activate a sensory system.

What is the formula for magnitude of a uniform electric field?
E = V/d
where v = voltage difference (potential difference) between plates
d = distance between plates

While running a marathon, a woman felt pain & a burning sensation in her legs. One reason for this is the conversion of pyruvate into lactic acid which the body does in order to...?
a.) Regenerate FADH from FADH2
b.) Regenerate FADH2 from FADH
c.) Regenerate NADH from NAD+
d.) Regenerate NAD+ from NADH
d.) Regenerate NAD+ from NADH

The ______ pathway mediates drug addiction.
The mesolimbic [dopamine] pathway mediates drug addiction.
Bonus: This pathway (also known as the rewards circuit) begins in the VTA.

What is the Water Dissociation constant?
Kw = 10-14 at 298K
1000
What is Poiseuille's Law? (Hint: this formula determines the rate of laminar flow)
Q = (πr4ΔP)/(8ηL)
P = pressure
η = viscosity of the fluid
L = length of pipe/tube

Almost all _______ (pick oxidizing or reducing) agents contain electronegative atoms such as oxygen. Why is this the case?
Oxidizing agents usually contain EN atoms such as oxygen.
Oxidizing agents are the ones that get REDUCED themselves. Getting reduced means that electrons are gained.

List three ways in which enzymes speed up a reaction:
I) They provide a favorable microenvironment in terms of charge or pH
II) They stabilize the transition state
III) They bring reactive groups nearer to one another

The activation-synthesis theory states what about dreams?
The activation-synthesis theory states that dreams are activated in the brainstem and synthesized in the cortex

What are two main formulas you could use if you wanted to find the pH of a solution and were only given the Acid or Hydrogen ion concentration?
pH = -log[H+]
or
[H+] = 10-pH
Note that pH = pKa + log [A-]/[HA] *could* work if you were given the pKa or could solve for it, but it's not the best formula to use here.
