Consider an atom with four energy levels, where the lowest energy is -10 eV and the highest level is 0 eV. Sketch an energy-level diagram that could produce the spectrum. What are the energies of the other two energy levels. (Note: there are more than two answers.)
A -2 eV and -5 eV
B -1 eV and -4 eV
C -1 eV and -6 eV
D -6 eV and -9 eV
E -7 eV and -3 eV

A national economy has (relatively) graduated, progressive taxation and provides income transfers to its poorest and most vulnerable members. It enacts legislation that reduces the highest marginal tax rates and limits the scope and scale of income transfers nationally and locally. Ceteris paribus, discuss: a) The effect on Aggregate Demand b) The effect on business expectations c) The effect on consumer spending in the short and the long term, and, therefore, d) The expected change to each domestic element of GDP (that is, excluding Net Exports).

You plan to borrow $75,000 to purchase a small yacht, 2014 Maritimo X50, with financing from Capital One Bank. You can afford to make monthly payments of $1,475, but no more. Assuming monthly compounding, what is the highest rate you can afford on a 60-month APR loan? What is the APR on this loan? What is the EAR on this loan? Prepare an amortization schedule on the 60-month yacht loan and determine the total interest paid after 5 months

i) Find the angular separation between the red hydrogen-α spectral line at 656 nm and the yellow sodium line at 589 nm if the two lines are observed in third order with a diffraction grating having 3 500 slits per cm. (Give the answer in degrees, correct to three significant figures.) [6]
(ii) Using the same diffraction grating as in (i) , what is the highest order that could possibly be observed using violet light of wavelength 420 nm?

Assuming you are write a program for the emergency room. You
maintain two queues. A regular FIFO queue for doctors. When a
doctor walked in, he/she will join this queue if there is no
patients waiting.
Otherwise, remove the patient with the highest priority and let the
doctor treat this patient.
A priority queue for patients. When a patient walked, input
patients name and priority. If doctor’s queue is not empty, remove
the first doctor and let this doctor server this patients.
Otherwise add this patient with the priority to the priority
queue.
