if slope of V vs t is positive it is accelerating if it is negative it is decelerating
Accuracy (validity) - ANSWER-the ability of an instrument to measure a true value
adiabatic process - ANSWER-Q=0
so delta U=-W
amplitude - ANSWER-Height of a wave (from the equilibrium position)
angular frequency - ANSWER-ω = 2πf= (2pi)/T
anmeters - ANSWER--used in series to measure current
at equal heights, speed and pressure are related how - ANSWER-they are inversely
related based off of venturi effect
beat frequency - ANSWER-The difference between the frequencies of the two
combining sound waves that make a beat.
fbeat= | f1- f2 |
beneficence - ANSWER-must be our intent to cause a net positive change for both the
study population and general population
Beta decay - ANSWER-emission of a beta particle which is an electron. (beta-)
in induced decay (positron emission), a positron is released which is mass of electron
but positive charge (beta +)
bias and confounding - ANSWER-bias is a result of flaws in the data collection phase of
an experimental or observational study. confounding is an error during analysis
bimodel distribution - ANSWER-frequency distribution in which there are two high points
rather than one
binary variables - ANSWER-can take on only two values. so yes or no type thing
Can electromagnetic waves travel through a vacuum? - ANSWER-yes, each oscillating
field causes oscillation in the other field completely independent of matter
,Can sound travel through a vacuum? - ANSWER-no
capacitors in parallel - ANSWER-C=C₁+C₂+C₃+...
capacitors in series - ANSWER-1/C=1/C₁+1/C₂+...
capillary hydrostatic pressure - ANSWER-promotes the movement of fluid out of the
capillaries
case-control study - ANSWER-start by identifying the number of subjects with or without
a particular outcome and then look backwards to assess how many subjects in each
group had exposure to a particular risk factor
categorical variable - ANSWER-places an individual into one of several groups or
categories. such as state of residence, socioeconomic status
centripital force equation - ANSWER-Fc= (mv^2)/r
change in internal energy - ANSWER-delta U = Q-W
Q is energy transferred into the system as heat
Chapter 10 - ANSWER-Chapter 10
Chapter 11 - ANSWER-Chapter 11
Chapter 12 - ANSWER-Chapter 12
Chapter 2 - ANSWER-Chapter 2
Chapter 3 - ANSWER-Chapter 3
Chapter 4 - ANSWER-Chapter 4
Chapter 5 - ANSWER-Chapter 5
Chapter 6 - ANSWER-Chapter 6
Chapter 7 - ANSWER-Chapter 7
Chapter 8 - ANSWER-Chapter 8
Chapter 9 - ANSWER-Chapter 9
chromatic aberration - ANSWER-the property of a lens whereby light of different colors
is focused at different places
,circular polarization - ANSWER-Due to the interaction of light with certain pigment or
highly specialized filters; constant amplitude but changing direction; helical orientation
closed boundaries - ANSWER--don't allow oscillation
-places of nodes
-ex: closed end of a pipe or secured ends of a string
closed system - ANSWER-can exchange energy but not matter with surroundings
cohort studies - ANSWER-the study of a group of people who share a common
characteristic and move forward in time as a unit.
-so subjects are sorted into groups based on differences in risk factors then assessed at
various intervals to determine outcome
Ex. 100 smokers and 100 nonsmokers followed for 20 years and count those who get
lung cancer
Conduction - ANSWER-direct transfer of energy from molecule to molecule through
molecular collisions
-so needs physical contact
-metals are good conductors because metallic bonds have a density of atoms
embedded in a sea of electrons
confidence - ANSWER-the probability of correctly failing to reject a true null hypothesis (
reporting no difference between two populations when one does not exist).
confounding - ANSWER-when an incorrect relationship is characterized
Conservation of mechanical energy - ANSWER-if there is no friction or air resistance,
the mechanical energy of a system changes only if the system does work on something
else or energy is added from outside the system.
U= delta U + delta K =0
constructive interference - ANSWER-The interference that occurs when two waves are
perfectly in phase and the amplitude of the resultant wave is the sum of the two
amplitudes
continuous variables - ANSWER-can assume an infinite number of values between any
two specific values. They are obtained by measuring. They often include fractions and
decimals. such as weight loss or percent improvement in cardiac output
Convention - ANSWER-transfer of heat by the physical motion of a fluid over a material
, converging mirrors - ANSWER-concave mirrors
conversion of mL to cm^3 - ANSWER-they are the same
conversions between Pa, mmHg, torr, and atm - ANSWER-1*10^5 Pa=760 mmHg=760
torr=1 atm
critical angle - ANSWER-the angle of incidence that produces an angle of refraction of
90 degrees
thetac= sin^-1 (n2/n1)
cross product - ANSWER-generate a third vector
AxB= |A| |B| sin theta
third vector C generated is going into or out of paper. Determine using the right handed
rule (put them in A direction, fingers in B direction and palm will tell C direction)
cross-sectional study - ANSWER-categorize patients into different groups at a single
point in time.
ex. determining the prevalence of lung cancer in smokers and nonsmokers at a given
point in time
current - ANSWER-the flow of positive charge so opposite the actual electron flow
current in parallel - ANSWER-It = I1 + I2+I3
current in series - ANSWER-the same everywhere
damping/ attenuation - ANSWER-a decrease in amplitude of a wave caused by an
applied or nonconservative force
describe the behavior of an insulator and conductor - ANSWER-insulators: not easily
distribute charge and not transfer that charge to another neutral object
conductors: distribute app evenly upon surface
destructive interference - ANSWER-- when waves are perfectly out of phase, the
amplitudes of the resultant wave is the difference between the amplitudes of interacting
waves
detection bias - ANSWER-Arises from educated professionals using their knowledge in
an inconsistent way by searching for an outcome disproportionately in certain
populations.
