Question 1

Formula for change in pressure

Answer 1

∆P = pg∆h

Question 2

Formula for potential energy of capacitor

Answer 2

U = (1/2)CV^2

Question 3

Capacitance and voltage formula

Answer 3

q = CV

Question 4

Doppler equation

Answer 4

f’ = f (v ± vd)/(v -+ vs)

• Top = towards (detector/source to object)
• Bottom = away
• vd = velocity of detector
• vs = velocity of source

Question 5

Intensity of sound

Answer 5

Power/Area

• Intensity is proportional to square of amplitude

Question 6

Lower Ksp => less or more soluble?

Answer 6

Lower concentration of products in solution => less soluble

Question 7

Index of refraction formula

Answer 7

n = c/v

Question 8

What does grinding a heterogenous catalyst do to amount of catalyst available?

Answer 8

Increases amount of available catalyst b/c greater exposed surface area => increased rate

Question 21

Where is glomerular filtrate most concentrated in kidney?

Answer 21

Medullary portion of collecting duct

Question 22

What type of lipids do lipid rafts have?

Answer 22

Cholesterol

Question 23

Is LDL more lipid or protein?

• HDL?

Answer 23

LDL = more lipid b/c lipids are less dense

HDL = more protein b/c ptns are more dense

Question 24

Initial filtration step in glomerulus of kidney occurs due to what?

Answer 24

Passive flow due to pressure difference

Question 25

Larger groups are (more/less) stable and (more/less) intimate

• Triads = more or less stable?

Answer 25

Larger = more stable and less intimate

• Triad = more stable than dyad b/c of additional social ties

Answer 26

Systematic observation of a complete social environment

Question 27

Critical angle of light ray

• What does it mean?

Answer 27

∂ = inverse sin(n2/n1)

• Minimum angle at which total internal reflection occurs

Question 28

Optics equation

Answer 28

1/f = 1/o + 1/i = 2/r

Question 29

If object is at center of curvature, its distance is ______

Answer 29

2f

Question 30

If image distance (i) is positive, image is ______

Answer 30

Real, inverted

Question 31

If image distance (i) is negative, image is ______

Answer 31

Virtual, upright

Question 32

Diverging systems only produce _____, _____ images

Answer 32

Virtual, upright

Question 33

______ of light ray traveling from one medium to another does not change

Answer 33

Frequency

Question 34

When is image produced by converging system real?

Virtual?

Answer 34

Real = distance greater than focal point

• PRIB
• Positive i, Real, Inverted, Beyond f

Virtual = distance less than focal point (b/w focal point and lens)

• LUVN
• Less than f, Upright, Virtual, Negative i

Question 35

As a slit narrows, light rays through the slit spread out more or less?

Answer 35

More => fringes spread further apart

Question 36
