9. Jerry is an employee of Baltimore Company. Baltimore Company pays employees the Friday after the wages are earned. Overtime in excess of 40 hours must be paid at 150% of the normal hourly rate. Social Security taxes are 6.2% and Medicare taxes are 1.45%. The federal unemployment tax rate is 1.0% and the state unemployment tax rate is 4.5%. Jerry’s wages, including the current pay period, will not exceed the limits for Social Security, Medicare and unemployment taxes. Jerry earns $19 per hour and worked 50 hours for the week ended January 13, 2019. Baltimore will withhold $220 federal income taxes. Use this information to determine the total payroll tax expense for Baltimore Company as related to Jerry’s earnings. (Round to the closest cent)

A salient-pole synchronous generator with saturated synchronous reactances Xd = 0.78 per unit and Xq = 0.63 per unit is connected to a rated-voltage infinite bus through an external impedance Xbus = 0.09 per unit.

a) Assuming the generator to be supplying 0.25 per unit rated real power, add a plot of the per-unit armature current as a function of field excitation as the field current is varied in the range for which the per-unit armature current is less than 1.0 per unit. Repeat for generator output powers of 0.50 and 0.75 per unit and add plots on the same axis.

HINT: The final result will be a plot of V-curves for this generator in this configuration.

1. You want to study the relationship between fat intake (g/day) and death rate in the Central Valley. Your friend, from PH 109, suggests that you conduct an ecological study first. You found the data and summarized it below. What is the association between fat intake (g/day) and death rate? Explain the ecological fallacy. Please show your scatter plot. (3 points)

Consider the following hypothetical economy. The production function is Cobb-Douglas and labor's share of income is 70%. All values are continuously compounded, annualized growth rates, in percent. Growth in real wages: 2.0

Growth in capital stock: 4.0

Growth in real rental rate of capital: 1.0

a. Using the information provided in the table above, your best estimate of growth in TFP is A. 1.4% B. 2.9% C. Not enough information to answer D. None of the above

b. Consider a small open economy. If national savings is 90, the trade surplus is 5 and the country's investment curve is described by i(r) = 110 * 500 r, then the world interest rate must be A. 5% B. 2% C. 1% D. Cannot tell

(A.) Phosgene is a deadly gas made up of carbon, oxygen and chlorine. Its density at 1.05 atm and 25C. is 4.24 g/L. Show that the molecular formula of phossgene is COCl₂ if it's compostion is 12.1 % carbon, 16.2% oxygen, and 71.7% chlorine by mass.

(B.) When exposed to UV light, phosgene, decomposes according to the reaction

COCl₂(g)------>CO(g)+Cl₂(g)

All the air removed from a 44.8 L flask. The flask is then filled the phosgene to a pressure of 1.0 atm at temperatue 0.C. The flask is selaed and exposed to UV light. What are the partial pressure of the CO and Cl₂ after the decompostion of phosgene is complete?

Pls show step by step on how each one is solved thank you in advance :)

Decide which of the following statements are true and which are false.

1. In order for two separate 1.0 L samples of O₂(g) and H₂(g) to have the same average velocity, the H₂(g) sample must be at a higher temperature than the O₂(g) sample.

2. At constant temperature, the heavier the gas molecules, the smaller the average kinetic energy.

3. As temperature decreases, the average kinetic energy of a sample of gas molecules increases.

4. At constant temperature, the lighter the gas molecules, the larger the average velocity.

5. Real gas molecules behave most ideally at low temperature and high pressure.

6. Ideal gas molecules have small volumes and exert weak attractive forces on one another.

Propane, C3H8, is used in many instances to produce heat by burning:

C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(g)

The standard enthalpy of reaction, ΔHrxn, is −2,044 kJ.

A swimming pool is 9.0 meters long, 1.0 meters deep and 3.0 meters wide is filled with water. The temperature of the water is 17°C, but the owner of the pool would like the temperature to be much warmer. The pool owner has a 120 gallon propane tank filled with 174 L of propane at 14.0 atm and 302 K. If the owner burns all of the propane in the tank, and assuming all of the heat goes to warming pool, what is the final temperature of the pool? The specific heat of water is 4.184 J/g · °C.

A municipal water authority is considering the installation of a new water system. Two options are being considered. The first option is a steel pipeline with an installation cost of $225 million. Annual maintenance and pumping costs begin at $15 million and increase by $1.0 million per year. The second option is a gravity fed concrete canal with an installation cost of $400 million. Annual maintenance costs begin at $0.5 million and increase by $0.4 million per year. The water system is expected to last 100 years and the interest rate is 5% per year compounded yearly. What is the present worth of the first option and second option? Report your answer in millions of dollars.

Please answer full question, and include cashflow diagram if possible.

In the car there is a circular tray that can rotate in horizontal plane above the seat. Let the car start moving in straight direction with acceleration of 0.5 m/s^2 relative to the ground. The tray on the seat starts to rotate simultaneously with the angular velocity ω = 2πt. At this moment, a mass of m = 0.01 kg the spider starts moving in the radial direction outward from the center of the tray with V = 0.1 m / s (t=second, w=rad/sec.). The magnitude of the forces acting on the spider in the spider's reference system. Find the directions at t = 1.0 sec. and the direction of the total force and find the size. If the static friction coefficient between the spider and the tray is µ = 0.2, find the maximum distance it can travel without slipping.
