From Practice Tests Flashcards
Distance (from acceleration)
d = (1/2)at^2
Power
P = IV
Wave Velocity
V = lambda f
Focal length - height relationship
d(object)/d(image) = h(object)/h(image)
Boyle’s law and exception
P1 V1 = P2 V2
Not true at elevated pressures
Normality
number of reactive moles of solute per liter = moles / L
Wave energy of a photon
E = hf C = f lambda E = hc / lambda h = planck's constant
Absorption
Absorption = Epsilon (constant) l(path) C(concentration)
When a metal is bonded to a non-metal
metal becomes positive
Sine wave
y = Y sin(kx - omega T)
Y = amplitude k = angular wave number = 2pi/wavelength omega = angular frequency x = displacement in direction of wave motion
Vasopressin
Anti-diuretic hormone, promotes water reabsorption in the collecting duct of the nephron, released by paraventricular and supraoptic nuclei of the hypothalamus, is a peptide
What kind of organ is the spleen?
a lymphoid organ
What happens when pH of solution is > than pKa of an acid side chain?
it will lose a proton and become negatively charged
What happens when the pH of a solution is < than the pKa of a basic side chain?
it will gain a proton and become positively charged
What will a nucleophile do?
It will try to become covalently bonded to an electronegative substrate
What is a zwitterion? What is one example?
It is an ion that can be positively and negatively charged. Free amino acids can do this due to their amino and carboxyl groups.
What is HCG and what releases it?
human chorionic gonadotropin, released by the placenta to maintain the corpus luteum
What do abnormally high estrogen levels indicate?
ovarian and adrenal tumors, also expressed in breast cancers
What are FSH and LH and what do they do?
spur the development of the follicle in the first half of the ovarian cycle
What does the corpus luteum produce?
progesterone and estrogen
Power dissipated
P = I^2 (current) R
Energy of a capacitor
E = (1/2) C (capacitance) V^2 (voltage)
Period length
T = 1 / f
What is positron decay?
add one neutron, lose one proton
