Flashcards in Review 9 Deck (36):
1

Formula for change in pressure

∆P = pg∆h

2

Formula for potential energy of capacitor

U = (1/2)CV^2

3

Capacitance and voltage formula

q = CV

4

Doppler equation

f' = f (v ± vd)/(v -+ vs)

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

5

Intensity of sound

Power/Area

- Intensity is proportional to square of amplitude

6

Lower Ksp => less or more soluble?

Lower concentration of products in solution => less soluble

7

Index of refraction formula

n = c/v

8

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

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

9

How many fused rings are in a steroid?

4

10

If a molecule is planar and hydrophobic, how will it pass through lipid membrane?

Simple diffusion

11

Where are secreted proteins (like insulin) cleaved into mature form?

Endomembrane system (ER, Golgi, vesicles, cell membrane, nuclear envelope)

12

Selye's general adaptation syndrome

Response to various stressors = similar

- Alarm, Resistance, Exhaustion

13

Mixed-methods study

Bringing together quantitative and qualitative methods

14

Diopter units

1/m

- Measure of lens strength

15

Maltose

2 glucoses

- Alpha 1-4

16

Lactose

Glucose + galactose

- Beta 1-4

17

Sucrose

Glucose + fructose

- Alpha 1-4

18

Cellulose

Repeating glucose

- Beta 1-4

19

Starch

Repeating glucose

- Alpha 1-4
- If highly branched => glycogen (alpha 1-6)

20

Gamma decay = emission of ____ by nucleus

Photon

21

Where is glomerular filtrate most concentrated in kidney?

Medullary portion of collecting duct

22

What type of lipids do lipid rafts have?

Cholesterol

23

Is LDL more lipid or protein?

- HDL?

LDL = more lipid b/c lipids are less dense

HDL = more protein b/c ptns are more dense

24

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

Passive flow due to pressure difference

25

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

- Triads = more or less stable?

Larger = more stable and less intimate

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

26

Ethnographic methods

Systematic observation of a complete social environment

27

Critical angle of light ray

- What does it mean?

∂ = inverse sin(n2/n1)

- Minimum angle at which total internal reflection occurs

28

Optics equation

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

29

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

2f

30

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

Real, inverted

31

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

Virtual, upright

32

Diverging systems only produce _____, _____ images

Virtual, upright

33

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

Frequency

34

When is image produced by converging system real?

Virtual?

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

35

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

More => fringes spread further apart

36

All images produced by plane mirrors = virtual or real?

Plane mirrors => virtual images
