A particle is found to carry the kinetic energy, K=(γ−1)mc2, which is equal to the energy of a photon. If the speed of the particle is v=0.500c, find the ratio of the wavelength of the photon to the de Broglie wavelength of the particle.

Repete |
0.97 |
9.5% |
Assume these securities are correctly priced. Based on the CAPM,
what is the expected return on the market? What is the risk-free
rate?

A battery charger used to recharge the NiMH (nickel metal-hydride) batteries used in a digital camera can deliver as much as 0.35 A of current to each battery. If it takes 145 minutes to recharge one battery, how much Ni(OH)2 (in grams) is oxidized to NiO(OH)?
H2O(l) + e? + NiO(OH)(s) ? OH?(aq) + Ni(OH)2(s)

Given this scenario, determine and map out the relevant cash flows for capital budgeting. Then use Excel to build your spreadsheet for the 10-year calculations, and after developing your estimates of each year's cash flow under the two scenarios, use the NPV method to determine what decision the company should make regarding the factory. Assume a 9% cost of capital. Explain your answer, and turn in the spreadsheet detailing your calculations.

Case study #2
Digestive system
Ms. K, age 79yrs old, has developed a partial obstruction in her colon. She was having difficulty with bowel movements and was nauseated, anorexic, and dehydrated. Surgery revealed diverticulitis with considerable fibrosis causing the obstruction. A colostomy was required.
Diverticulitis - Diverticulosis happens when pouches (diverticula (Links to an external site.)Links to an external site.) form in the wall of the colon (Links to an external site.)Links to an external site.. If these pouches get inflamed or infected, it is called diverticulitis (Links to an external site.)Links to an external site.. Diverticulitis can be very painful.

The choices describe possible scenarios and outcomes from Gram staining with standard stains (e.g., crystal violet and safranin). Match the scenario with the most likely outcome and explain why this occurs.
|
A. A gram-negative cell is stained, but the ethanol step is skipped. |
i. The cell will probably appear pink, which will not correctly indicate its cell wall structure. |
|
B. A gram-positive cell with a severely damaged cell wall is stained. |
ii. The cell will appear pink. |
|
C. A healthy gram-negative cell is stained. |
iii. The cell will appear purple/violet. |
|
D. A healthy gram-positive cell is stained. |
iv. The cell will probably appear purple/violet, which will not correctly indicate its cell wall structure. |
