A 54.1 mg sample of sodium perchlorate contains radioactive chlorine-36 (whose atomic mass is 36.0 amu).

1. If 29.6% of the chlorine atoms in the sample are chlorine-36 and the remainder is naturally occurring nonradioactive chlorine atoms, how many disintegrations per second are produced by this sample?

The half-life of chlorine-36 is 3.0×105 yr.

Oranges are very susceptible to cold weather, and long exposure to subfreezing temperatures can destroy them. Consider an 8 cm diameter orange (assume it is an idealised sphere) that is initially at 15oC. A cold front moves in one night, and the ambient temperature suddenly drops to -8.5oC, with a heat transfer coefficient of 7 W m-2 K−1 . Using the properties of water for the orange and assuming the ambient conditions to remain constant for 2.5 hours before the cold front moves out, determine temperatures at: ro = 0.0 cm (i.e., centre of the orange); ro = 1.0 cm; ro = 2.0 cm; ro = 3.0 cm; ro = 4.0 cm

At a fixed temperature, equal moles of N₂ (g) and F₂ (g) are mixed in a constant pressure container (the volume of the container changes in order to keep the pressure at a constant value). The N₂ (g) and F₂ (g) are allowed to react, producing NF₃ (g):

N₂ (g) + 3F₂ (g) ? 2 NF₃ (g)

If the initial volume of the container, before any reaction takes place, is 4.10 L, determine the volume of the container after the N₂ (g) and F₂ (g) have reacted to completion.

The final volume will be  L

Jeremy and Alyssa Johnson have been married for five years and do not have any children. Jeremy was married previously and has one child from the prior marriage. He is self-employed and operates his own computer repair store. For the first two months of the year, Alyssa worked for Office Depot as an employee. In March, Alyssa accepted a new job with Super Toys Inc. (ST), where she worked for the remainder of the year. This year, the Johnsons received $273,000 of gross income.

1. Expenses associated with Jeremy’s store include $44,500 in salary (and employment taxes) to employees, $50,400 of supplies, and $19,800 in rent and other administrative expenses.
2. As a salesperson, Alyssa incurred $2,180 in travel expenses related to her employment that were not reimbursed by her employer.
3. The Johnsons own a piece of raw land held as an investment. They paid $680 of real property taxes on the property and they incurred $290 of expenses in travel costs to see the property and to evaluate other similar potential investment properties.
4. The Johnsons own a rental home. They incurred $8,680 of expenses associated with the property.
5. Jeremy paid $4,680 for health insurance coverage for himself (not through an exchange). Alyssa was covered by health plans provided by her employer, but Jeremy is not eligible for the plan until next year.
6. Jeremy paid $2,680 in self-employment taxes ($1,340 represents the employer portion of the self-employment taxes).
7. Jeremy paid $5,360 in alimony and $3,270 in child support from his prior marriage (divorced in 2010).
8. The Johnsons donated $2,180 to their favorite charity.

Determine the Johnson's AGI given the above information:

Jackson County Senior Services is a nonprofit organization devoted to providing essential services to seniors who live in their own homes within the Jackson County area. Three services are provided for seniors—home nursing, Meals On Wheels, and housekeeping. Data on revenue and expenses for the past year follow:

*Allocated on the basis of program revenues.

The head administrator of Jackson County Senior Services, Judith Miyama, considers last year’s net operating income of $32,800 to be unsatisfactory; therefore, she is considering the possibility of discontinuing the housekeeping program.

The depreciation in housekeeping is for a small van that is used to carry the housekeepers and their equipment from job to job. If the program were discontinued, the van would be donated to a charitable organization. None of the general administrative overhead would be avoided if the housekeeping program were dropped, but the liability insurance and the salary of the program administrator would be avoided.

Required:

1-a. What is the financial advantage (disadvantage) of discontinuing the Housekeeping program?

1-b. Should the Housekeeping program be discontinued?

2-a. Prepare a properly formatted segmented income statement.

2-b. Would a segmented income statement format be more useful to management in assessing the long-run financial viability of the various services?
