What is the energy of the photons emitted by the LED at a frequency of 610 THz?
(Note: h = 6.6 × 10-34 J·s)
A.9.2 × 10-12 J
B.1.6 × 10-16 J
C.1.1 × 10-18 J
D.4.0 × 10-19 J - correct-answer -Multiply the two numbers because...
e=Hf
h=planks constant
f= frequency
e=energy
(6e-34)(6e14)= 36e-20= 3.6e-19----> closest answer is D.
**tetra is e12, but added two more exponents since you started with 610!!

What is the relationship between Pp, PMPA, and Pd?
A.Pp = PMPA + 3Pd
B.Pp = 3PMPA + Pd
C.Pp = 3PMPA − 3Pd
D.Pp = PMPA − 3Pd
Passage:
PMPA = Pd + (Ps - Pd)/3
Pp = Ps - Pd - correct-answer -c.
3PMPA= Pd+ (Ps-Pd)
*you see from the first equation that Pd is directly related to 3PMPA put three in
front of it.
*also, C is the only answer choice with a -pd answer and a 3pmpa
What percentage of standard atmospheric pressure is the pulse pressure of a
healthy adult?
A.10%
,3|Page
B.6%
C.2%
D.1%
Passage: Ps = 120 mmHg and Pd = 75 mm Hg
pulse pressure Pp is defined as
Pp = Ps - Pd - correct-answer -SO. Let's look at this. Pulse pressure is the difference
between these two. (120-75)= 45
Standard atmospheric pressure is 760 mm hg.
round--->45/760 = 9/152 ~ 9/150 = 3/50 = 6/100 = 6%
What fraction of a 15O sample decays in 10 min?
A.1/8
B.9/16
C.3/4
D.31/32
Passage: 15O (with a half-life T1/2 = 2 min) - correct-answer -There are 5 half-lives
in 10 minutes.
(1/2)^5=1/32
, 4|Page
Only 1/32 will remain of the sample. So, 31/32 of the sample decayed.
What is the work generated by a healthy adult who circulates 9 L of blood through
the brachial artery in 10 min?
A.2 kJ
B.12 kJ
C.20 kJ
D.120 kJ - correct-answer -***want minutes in seconds
9L= 900ml
900ml corresponds to 200w
Power= work/time
200w= work/600 seconds
200x600=120,000
120 kj
Compared to micellular Compound 1, Compound 2 is structurally more rigid as a
result of what type of interaction?
A.Intermolecular hydrogen bonding
B.Intermolecular covalent bonding
C.Intramolecular hydrogen bonding
