Question 6:

A market gardener is planning a planting scheme for the new growing season, and there are 12 different crops to choose from – 8 of which are vegetables and 4 of which are grains.

1. a) Calculate the number of different ways he can select 7 crops to plant, if there are no restrictions.
2. b) Redo (a), with the extra restriction that he must select at most 2 grain crops.
3. c) Say that he has selected the following 7 crops: tomatoes, carrots, peas, radishes, beans, lettuce, cilantro. He wishes to plant these in 7 adjacent rows, with 1 crop in each row. Calculate the number of different ways he can arrange these rows, if there are no other restrictions.
4. d) Redo (c), with the extra restriction that the tomatoes and carrots must be planted in adjacent rows.
5. e) Redo (d), with the further extra restriction that the peas and beans must not be planted in adjacent rows.
6. f) Redo (e), with the further extra restriction that the 7 crops must be planted in a circle, instead of in adjacent rows.

1- Briefly define the following types of primate behavior and give an example of each as

discussed in class, in your textbook, and/or as seen in observations in films: dominance,

aggression, affiliative, tool use, and communication.

2- Discuss the structural as well as behavioral changes that are the result of bipedalism.

3- Is it possible to use bone trauma to help solve a forensic case?

Please answer All of them. Thank you!

Show how to obtain equation (4) from equations (1), (2), and (3). Please show each step.

(1) Tr=Iα
(2)α=a/r
(3) mg-T-f=ma

(4) I=mr²[(g/a)-1-(f/ma)]

A parallel-plate capacitor has capacitance 4.50 μF.

(a) How much energy is stored in the capacitor if it is connected to a 8.00-V battery?
μJ

(b) If the battery is disconnected and the distance between the charged plates doubled, what is the energy stored?
μJ

(c) The battery is subsequently reattached to the capacitor, but the plate separation remains as in part (b). How much energy is stored?
μJ

CVP Analysis of Multiple Products

Steinberg Company produces commercial printers. One is the regular model, a basic model that is designed to copy and print in black and white. Another model, the deluxe model, is a color printer-scanner-copier. For the coming year, Steinberg expects to sell 100,000 regular models and 20,000 deluxe models. A segmented income statement for the two products is as follows:

Required:

1. Compute the number of regular models and deluxe models that must be sold to break even. Round your answers to the nearest whole unit.

2. Using information only from the total column of the income statement, compute the sales revenue that must be generated for the company to break even. Round the contribution margin ratio to four decimal places. Use the rounded value in the subsequent computation. (Express as a decimal-based amount rather than a whole percentage.) Round the amount of revenue to the nearest dollar.

Consider a sharp crested (uncontracted horizontal) rectangular weir 1.0 m long and 0.8 m high. The channel receives a flow of 0.3 m3 /sec. What will be the depth and velocity in the channel?

Hydrogen is mixed with a stoichiometric amount of oxygen in a 1 L volume at 100 kPa at 300 K. All of the hydrogen is burned at constant but heat leaves the system such that the final temperature is still 300 K. What is the amount of heat released and what is the final pressure in the container?

Several items are omitted from the income statement and cost of goods manufactured statement data for two different companies for the month of May.

The density of water at room temperature is less than the assumed 1.0 g/mL used in the calculations for determining the enthalpy of neutralization. How will this small (but real) assumption affect the reported enthalpy of neutralization for the strong acid-weak base reaction? Explain.

A trapezoid-shaped potato with base lengths of 1.5 cm and 2.0 cm respectively and a height/thickness of 0.5 cm was dried at a temperature of 70 ^oC in a convective oven for 24 h, if the surface temperature of the potato remained at 65 ^oC throughout the drying operation, describe the different changes that occurs during the constant and falling rate periods. If the convective heat transfer coefficient of stem/water is given as 850 W/m^2oC, calculate the amount of heat transferred into the potato
