Compared to gross growth efficiency, energy absorption efficiency
a. must be lower.
b. must be higher.
c. can be lower but does not have to be.
d. can be higher but does not have to be.
Answer - Compared to gross growth efficiency, energy absorption efficiency - must be higher.
Gross growth efficiency is the relative percentage of carbon that goes into each process. With the absorption of energy, energy absorption efficiency occurs.
3. Why doped polymers exhibit absorption peaks in much lower energy compared to their pristine or undoped states?
a) Is the energy absorption associated with bands in an infrared spectrum of higher or lower energy than the lines appearing in a visible line spectrum. Explain? b) Identify the type of energy transition occuring in a molecule that causes a band to appear in an infrared spectrum. c) Identify the type of energy transition occuring in an atom that causes a line to appear in a visible line spectrum.
1. (a) Why does buta-1,3-diene (max 217 nm) have a longer-wavelength (lower-energy) UV-Vis absorption peak as compared to ethene (max 171 nm)? Include an energy level diagram with your answer. (b) What would you expect to happen as you add on to this structure with additional double bonds? Hint: consider the total number of p atomic orbitals contributing to each molecule, as depicted below. ?-? Ethene Butadiene
When computing economic growth, changes in nominal gross domestic product (GDP) must be adjusted to reflect population growth because: Choose one: A. changes in population tend to have no effect on standard of living. B. if real GDP remains the same, an increase in the population actually means a raised average standard of living .C. an increase in the population will tend to decrease average prices. D. an increase in population will tend to reduce nominal GDP. E. if real...
Q2- Why does a monopoly result in a loss of efficiency compared to a perfect competition framework? Can you think of a government policy which would result in a loss of efficiency?
True statements about the absorption and emission of energy by an atom include which of the following? I. An atom can only absorb photons of light that have certain specific energies. II. An atom can emit photons of light of any energy. III. At low temperature, the lines in the absorption spectrum of an atom coincide with the lines in its emission spectrum that represent transitions to the ground state. A. I only B. III only C. I and III...
Hibbert plc has calculated their gross profit % to be 45% in 2014 compared to 37% in 2013. Which of the following! statements is unlikely to be an explanation for the improved results? Select one: a. A cheaper supplier of raw material was found O b. Change to the minimum wage increased the production labour rate per hour C.

42. On a given aggregate demand curve, if the rate of spending growth is 10% and the growth rate of the money supply is 2%, then the velocity of money must be growing at: A) 5% B) 8%. 12%. D) 20% 43. According to the quantity theory of money, if both the growth rate of the money supply and the velocity of money are fixed, then a higher inflation rate means: A) a higher real growth rate. B) no change...
