You need to use your cell phone, which broadcasts an 833 MHz signal, but you're in an alley between two massive, radio-wave-absorbing buildings that have only a 15 m space between them.

What is the angular width, in degrees, of the electromagnetic wave after it emerges from between the buildings?

Thehormone estrogen is produced in the ovaries of females and elsewhere in the body in men and post-
menopausal women, and it is also administered in estrogen replacement therapy, a common treatment
for women who have undergone a hysterectomy. Unfortunately, it also binds to estrogen receptors in
breast tissue and can activate cells to become cancerous. Tamoxifen is a drug that also binds to estrogen
receptors but does not activate cells, in effect blocking the receptors from access to estrogen and
inhibiting the growth of breast-cancer cells.
Tamoxifen is administered in tablet form. In the manufacturing process, a finely ground powder
contains tamoxifen (tam) and two inactive fillers—lactose monohydrate (lac) and corn starch (cs). The
powder is mixed with a second stream containing water and suspended solid particles of polyvinylpyrro-
lidone (pvp) binder, which keeps the tablets from easily crumbling. The slurry leaving the mixer goes to a
dryer,inwhich94.2%ofthewaterfedtotheprocessisvaporized.Thewetpowderleavingthedryercontains
8.80wt% tam, 66.8% lac, 21.4% cs, 2.00% pvp, and 1.00% water. After some additional processing, the
powder is molded into tablets. To produce a hundred thousand tablets, 17.13kg of wet powder is required.
(a) Taking a basis of 100,000 tablets produced, draw and label a process flowchart, labeling masses of
individual components rather than total masses and component mass fractions. It is unnecessary to
label the stream between the mixer and the dryer. Carry out a degree-of-freedom analysis of the
overall two-unit process.
(b) Calculate the masses and compositions of the streams that must enter the mixer to make 100,000
tablets.
(c) Why was it unnecessary to label the stream between the mixer and the dryer? Under what
circumstances would it have been necessary?
(d) Go back to the flowchart ofPart (a). Without using the mass of the wet powder (17.13kg) or any of
the results from Part (b) in your calculations, determine the mass fractions of the stream
components in the powder fed to the mixer and verify that they match your solution to Part (b).
(Hint: Take a basis of 100kg of wet powder.)
(e) Suppose a student does Part (d) before Part (b), and re-labels the powder feed to the mixer on the
flowchart of Part (a) with an unknown total mass (m1) and the three now known mole fractions.
(Sketch the resulting flowchart.) The student then does a degree-of-freedom analysis, counts
four unknowns (the masses of the powder, pvp, and water fed to the mixer, and the mass of
water evaporated in the dryer), and six equations (five material balances for five species and the
percentage evaporation), for a net of 2 degrees of freedom. Since there are more equations than
unknowns, it should not be possible to get a unique solution for the four unknowns. Never-
theless, the student writes four equations, solves for the four unknowns, and verifies that all of the balance equations are satisfied. There must have been a mistake in the degree-of-freedom
calculation. What was it?

Equivalent Units and Related Costs; Cost of Production Report; Entries

Dover Chemical Company manufactures specialty chemicals by a series of three processes, all materials being introduced in the Distilling Department. From the Distilling Department, the materials pass through the Reaction and Filling departments, emerging as finished chemicals.

The balance in the account Work in Process—Filling was as follows on January 1:

The following costs were charged to Work in Process—Filling during January:

During January, 57,600 units of specialty chemicals were completed. Work in Process—Filling Department on January 31 was 5,000 units, 40% completed.

Required:

1. Prepare a cost of production report for the Filling Department for January. If an amount is zero, enter "0". If required, round your cost per equivalent unit answers to two decimal places.

Feedback

1. Calculate equivalent units for materials and conversion costs. Calculate the cost per equivalent unit for materials and conversion costs. Calculate the costs assigned to the beginning inventory, the units started and completed, and the ending inventory.

2. Journalize the entries for (1) costs transferred from Reaction to Filling and (2) the cost transferred from Filling to Finished Goods.

Feedback

2. Remember that there are three types of inventory; materials, work in process, and finished goods. What costs are captured in the work in process account? Are these units 100% complete or are they being transferred to another department?

3. Determine the increase or decrease in the cost per equivalent unit from December to January for direct materials and conversion costs. If required, round your answers to two decimal places.

4. Discuss the uses of the cost of production report and the results of part (3).

The cost of production report may be used as the basis for allocating product costs between   and  . The report can also be used to control costs by holding each department head responsible for the units entering production and the costs incurred in the department. Any differences in unit product costs from one month to another, such as those in part (3), can be studied carefully and any significant differences investigated.

Feedback

3 and 4. Compare the costs per equivalent unit for December and January. Review the benefits of the cost of production report.

Discuss applications on Kali Linux that can be used to conduct an attack. Provide information on a specific tool such as SQL Map and steps that an attacker could use to carry out a successful attack.

Reactant A decomposes by three simultaneous reactions to form three products, one that is desired, B, and two that are undesired, X and Y. These gas-phase reactions, along with the rate laws, are as follows. (40pts) 1) A→X -r1A = rX= k1 = 0.0001 mol dm-3 sec-1 2) A→B -r2A = rB = k2 CA 2 = (0.0015 s-1 ) CA 2 3) A→Y -r3A=rY=k3 = 0.008 dm3 mol-1 sec-1 The specific reaction rates are given at 300 K and the activation energies for reactions (1), (2), and (3) are E1 = 10,000 kcal/mole, E2 = 12,000 kcal/mole, and E3 = 20,000 kcal/mole. (a) How, and under what conditions (e.g., reactor type(s), temperature, concentrations), should the reaction be carried out to maximize the selectivity of species B for an entering concentration of species A of 0.4 M and a volumetric flow rate of 2.0 dm3 /s? (b) Design the suitable type of reactor assuming there is no pressure drop.

Write a program that asks the user to enter an unsigned number and read it. Then swap the bits at odd positions with those at even positions and display the resulting number. For example, if the user enters the number 9, which has binary representation of 1001, then bit 0 is swapped

with bit 1, and bit 2 is swapped with bit 3, resulting in the binary number 0110. Thus, the

program should display 6.

1)A projectile is launched at some angle above the horizontal. It is in the air for 3.3 seconds before returning to the same height it was launched. If its range is 57 meters in the +x direction, what is the x component of its velocity in m/s when it is at its maximum height?

2)A projectile is launched at 33 degrees above the horizontal at a speed of 29 m/s from the edge of a building which is 69 meters above the ground. What
is the maximum height the projectile reaches above the ground in meters?

3)A projectile is launched at 25 degrees below the horizontal at a speed of 37 m/s from the edge of a building which is 32 meters above the ground. What
speed (magnitude of velocity) does it strike the ground in m/s?

Government and Not for Profit Accounting Even programs involving relatively subjective judgments can readily be audited.

A Department of Housing and Urban Development (HUD) program is aimed at conserving and rehabilitating blighted but salvageable urban areas. One element of the program provides that HUD will make rehabilitation grants and low-interest loans to property owners to help them finance the repairs needed to bring their properties into compliance with housing codes.

When Congress authorized the program, it did not establish specific criteria as to what constitutes a "blighted but salvageable" area; it left that up to HUD.

A preliminary survey by the GAO has indicated that HUD is directing funds to areas that were far too deteriorated for conservation and rehabilitation to work.

Suppose that you are assigned to the engagement. Outline an approach that you would take to support (or reject) the findings of the preliminary survey.

A point charge q is placed a distance L from a grounded plate (z=0). Calculate the charge distribution on the plate.
