The illustration shows the
spectrum of electromagnetic radiation emitted by a blackbody at two
different Kelvin temperatures. The range of visible frequencies
(those that can be detected by the human eye) is also shown.(a) No
matter what the value of the Kelvin temperature T, the
spectrum decreases to zero at very high frequencies. Why is
this?(i) At very high frequencies the photon energy is very small
compared to kT.(ii) At very high frequencies the photon
energy is very large compared to kT.(ii) At very high
frequencies there are very few standing wave patterns in a
blackbody cavity.(iv) Both (i) and (iii) are true.(v) Both (ii) and
(iii) are true.
No matter what the value of the Kelvin temperature T, the spectrum decreases to zero at very high frequencies.
Beacause
At very high frequencies the photon energy is very large compared to kT

blanks in each of the following statements with the word
red, the word violet, the word infrared,
the word ultraviolet, or the phrase don’t
know.(i) For the lower-temperature blackbody, in the visible
range (from red to violet) the blackbody emits more __________
light than it does __________ light. Hence to the naked eye the
color of the light emitted by this lower-temperature blackbody will
be __________, even though the frequency at which this blackbody
emits most...

2. Derive the temperature profile T (R) for a spherical blackbody and a disk blackbody (assuming constant luminosity in both cases). Hint: this is similar to what we saw in class, but solving for T instead of R! Make a plot of T(R) vs. R, and show both profiles on the same plot. (3 pts) 3. Suppose an electron emitted a bremsstrahlung photon around an iron nucleus, instead of a free proton. Would the X-ray energy of the photon be...
1. According to the paper, what does lactate dehydrogenase
(LDH) do and what does it allow to happen within the myofiber? (5
points)
2. According to the paper, what is the major disadvantage of
relying on glycolysis during high-intensity exercise? (5
points)
3. Using Figure 1 in the paper, briefly describe the different
sources of ATP production at 50% versus 90% AND explain whether you
believe this depiction of ATP production applies to a Type IIX
myofiber in a human....
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
