AAMC Practice Flashcards
1
Q
equation: pressure under the surface of a liquid
A
P = ρgh
P = pressure ρ = density g = acceleration due to gravity (9.8) h = depth of liquid
2
Q
buoyant force equation
A
F = -ρgV
F = buoyant force exerted by the fluid onto the floating object ρ = density of liquid g = acceleration due to gravity (9.8) V = fluid volume
3
Q
Archimede’s Principle
A
the buoyant force of a fluid is equal to the weight of the displaced fluid
when an object is immersed fully or partially in a fluid, the upward force applied by the fluid on the object is the same as the weight of the fluid displaced by the object
4
Q
determine frequency given wavelength
A
f λ= c
f = frequency (s-1 or Hz)
λ = wavelength (m)
c = speed of light (m/s)
5
Q
Hz units
A
1/seconds or s-1
6
Q
speed of light
A
7
Q
electric field units
A
volts / meter
8
Q
1 volt / meter =
A
1 Newton / coulomb
9
Q
newton units
A
10
Q
volt units
A
joules / coulomb
11
Q
1 joule =
A
1 newton meter
12
Q
in phase vs out of phase (waves)
A
