Question 1

equation: pressure under the surface of a liquid

Answer 1

P = ρgh

P = pressure
ρ = density
g = acceleration due to gravity (9.8)
h = depth of liquid

Question 2

buoyant force equation

Answer 2

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

Question 3

Archimede’s Principle

Answer 3

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

Question 4

determine frequency given wavelength

Answer 4

f λ= c

f = frequency (s-1 or Hz)

λ = wavelength (m)

c = speed of light (m/s)

Question 5

Hz units

Answer 5

1/seconds or s-1

Question 6

speed of light

Answer 6

Question 7

electric field units

Answer 7

volts / meter

Question 8

1 volt / meter =

Answer 8

1 Newton / coulomb

Question 9

newton units

Answer 9

Question 10

volt units

Answer 10

joules / coulomb

Question 11

1 joule =

Answer 11

1 newton meter

Question 12

in phase vs out of phase (waves)

Answer 12

Question 13

wavelength

Answer 13
