Sailplanes use updrafts to stay aloft for hours at a time. Near one particular airfield, a stone quarry (with very dark rocks) surrounded by a wooden area provides a particularly regular source for updrafts on hot days. With your knowledge of heat transfer, explain the processes that create the updraft

What happens to the light [energy] after it enters an eye and hits the rods and cones? I presume the energy becomes electrical, and it must be near 100% perfect, else our eyes would heat up? Or am I missing something?

The motivation of this question is solar panel technology.

Briefly discuss the main difference between the valence bond and molecular orbital treatments of electronic states in molecules. Which is a better representation of molecules with all bond lengths at their equilibrium separation? And which is better when one or more bond lengths are stretched near their dissociation limit? Explain.

For each of the following, would a score of X = 85 be considered a central score (near the middle of the distribution) or an extreme score (far out in the tail of the distribution)? µ =75 and σ = 15 µ =80 and σ = 2 µ =90 and σ = 20 µ =93 and σ = 3

What are the main characteristics of born global firms? Evaluate the drivers of market globalization that have allowed born global firms such as Instagram to internationalize at, or near, their founding. What advantages do you think a young company can gain by entering international markets soon after their founding?

Experiences with a school-age child whose family is at or near the poverty level. How did poverty impact their life? Include examples of strengths within the child and family, or relationships and resources available to them outside of the family that may have helped them overcome some of the obstacles to their success.

Pharoah Legler requires an estimate of the cost of goods lost by fire on March 9. Merchandise on hand on January 1 was $34,200. Purchases since January 1 were $64,800; freight-in, $3,060; purchase returns and allowances, $2,160. Sales are made at 33 1/3% above cost and totaled $99,000 to March 9. Goods costing $9,810 were left undamaged by the fire; remaining goods were destroyed.

Compute the cost of goods destroyed. (Round gross profit percentage and final answer to 0 decimal places, e.g. 15% or 125.)

Compute the cost of goods destroyed, assuming that the gross profit is 33 ¹/₃% of sales. (Round ratios for computational purposes to 5 decimal places, e.g. 78.72345% and final answer to 0 decimal places, e.g. 28,987.)

The following information is available for three companies:

Required
a. Determine the annual before-tax interest cost for each company in dollars.

b. Determine the annual after-tax interest cost for each company in dollars. (Round your answers to the nearest dollar amount.)

c. Determine the annual after-tax interest cost for each company as a percentage of the face value of the bonds. (Round your answers to 1 decimal place.)
