Mary Wade owns a small business that rents parking spaces to students at the local university. Mary’s typical rental contract requires the student to pay the year’s rent of $720 ($60 per month) in advance. When Mary prepares financial statements at the end of December, her accountant requires that Mary spread the $720 over the 12 months that a parking space is rented. Therefore, Mary can recognize only$240 revenue (4 months) from each contract in the year the cash is collected and must defer recognition of the remaining $480 (8 months) to next year. Mary argues that getting students to agree to rent the parking space is the most difficult part of the activity so she ought to be able to recognize all$720 as revenue when the cash is received from a student.

An old manuscript reveals that a landowner in the time of King Arthur held 3.00 acres of plowed land plus a livestock area of 25.0 perches by 4.00 perches. What was the total area in the more modern unit of square meters? Here, 1 acre is an area of 40 perches by 4 perches, 1 rood is an area of 40 perches by 1 perch, and 1 perch is the length $16.5 \mathrm{ft}$.

Modern halogen lightbulbs allow their filaments to operate at a higher temperature than the filaments in standard incandescent bulbs. For comparison, the filament in a standard lightbulb operates at about $2900 \mathrm{~K}$, whereas the filament in a halogen bulb may operate at $3400 \mathrm{~K}$. The human eye is most sensitive to a frequency around $5.5 \times 10^{14} \mathrm{~Hz}$. Which bulb produces a peak frequency closer to this value?

You design an experiment to test the effectiveness of a vaccine against a strain of influenza. In the experiment, 100,000 people receive the vaccine and another 100,000 people receive a placebo. Identify a potential problem with the experimental design. Then describe how you can improve it.

Design a brochure that explains information about each biological molecule discussed in this chapter.

You want to create a circuit from the following materials: a battery, copper wire, a switch, and three light bulbs. Design your circuit so that the light bulbs shine as brightly as possible. Draw a circuit diagram to reflect your design.

The following situations describe decision scenarios that could use managerial accounting information:

1. The manager of High Times Restaurant wants to determine the price to charge for various lunch plates.
2. By evaluating the cost of leftover materials, the plant manager of a precision tool facility wants to determine how effectively the plant is being run.
3. The division controller of West Coast Supplies needs to determine the cost of products left in inventory.
4. The manager of the Maintenance Department of a large manufacturing company wants to plan next year's anticipated expenditures.

For each situation, discuss how managerial accounting information could be used.

Solve the given problems.

In a modern hotel, where the elevators are directly observable from the lobby area (and a person can see from the elevators), a person in the lobby observes one of the elevators rising at the rate of $12.0$ ft/s. If the person was $50.0$ ft from the elevator when it left the lobby, how fast is the angle of elevation of the line of sight to the elevator increasing $10.0$ s later?

The first bridge over the Piscataqua River, built in $1794$, was the longest bridge in the world. The modern bridge, completed in $1971$, is not the world's longest, but it is well known for its elegant symmetric design. The bridge connects Kittery, Maine with Portsmouth, New Hampshire.

Does the Piscataqua River Bridge have any lines of symmetry? If so, make a simple sketch of the bridge and draw all of its lines of symmetry.
