Assuming a reciever is located 10km from a 50w
transmitter. the carrier frequency is 1900Mhz, free Gr=2,
find
I) the power at the receiver,
II) the magnitude of the E-field at the receiver antenna,
iii) the open circuit RMS voltage applied to the receiver input
assuming that the receiver antenna has 50ohms and is match to the
receiver .
iv) find the received power at the mobile using the two- ray ground
reflection model assuming the height of the transmitting antenna is
50m, recieving antenna is 1.5m above the ground , and the ground
reflection is -1

You are serving on a jury. A plaintiff is suing the city for injuries sustained after a freak street-sweeper accident. In the trial, doctors testified that it will be five years before the plaintiff is able to return to work. The jury has already decided in favor of the plaintiff. You are the foreperson of the jury and propose that the jury give the plaintiff an award to cover the following: |
| (a) |
The present value of two years’ back pay. The plaintiff’s annual salary for the last two years would have been $67,000 and $70,000, respectively. |
| (b) |
The present value of five years’ future salary. You assume the salary will be $73,000 per year. |
| (c) | $245,000 for pain and suffering. |
| (d) |
$40,000 for court costs. |
| Assume the salary payments are equal amounts paid at the end of each month. |
|
If the interest rate you choose is an EAR of 8 percent, what is the size of the settlement? |

Note: Please acknowledge the list of possible answers for each question. The CORRECT answer is one of those answers. An answer that does NOT match one of the listed answers is INCORRECT.
Question:
Part A) On a loop-the-loop of diameter D = 37.8 ± 0.5 cm, what is the expected minimum starting height hthat the ball must be released from to make it around the loop?
Possible answers: 0.601, 0.903, 0.506, 0.571, 0.806, 0.51, 0.822, 0.849, 0.667, 0.927
Part B) On a loop-the-loop of 45.0 ± 0.7 cm in diameter, what is the uncertainty in the expected minimum starting height σh that the ball must be released from to make it around the loop?
Possible answers: 0.003, 0.004, 0.005, 0.008, 0.009, 0.011. 0.001
Part C) If, on the loop-the-loop of diameter 46.3 ± 0.5 cm, the minimum height found by testing is hmeas = 73.5 ± 1 cm, what fraction of the ball's energy is lost to friction and wobble?
Possible answers: 0.183, 0.15, 0.322, 0.222, 0.25, 0.082, 0.223, 0.138, 0.144, 0.177
Part D) If, on the loop-the-loop of diameter 43.1 ± 0.7 cm, the minimum height found by testing is hmeas = 78.5 ± 0.6 cm, what is the uncertainty in the fractional energy is loss?
Possible answers: 0.005, 0.013, 0.004, 0.01, 0.014, 0.009, 0.011, 0.012, 0.006, 0.007

| J. Smythe, Inc., manufactures fine furniture. The company is deciding whether to introduce a new mahogany dining room table set. The set will sell for $8,000, including a set of eight chairs. The company feels that sales will be 2,450, 2,600, 3,150, 3,000, and 2,750 sets per year for the next five years, respectively. Variable costs will amount to 47 percent of sales and fixed costs are $1.98 million per year. The new dining room table sets will require inventory amounting to 8 percent of sales, produced and stockpiled in the year prior to sales. It is believed that the addition of the new table will cause a loss of sales of 650 dining room table sets per year of the oak tables the company produces. These tables sell for $5,300 and have variable costs of 42 percent of sales. The inventory for this oak table is also 8 percent of sales. The company believes that sales of the oak table will be discontinued after three years. J. Smythe currently has excess production capacity. If the company buys the necessary equipment today, it will cost $15 million. However, the excess production capacity means the company can produce the new table without buying the new equipment. The company controller has said that the current excess capacity will end in two years with current production. This means that if the company uses the current excess capacity for the new table, it will be forced to spend the $15 million in two years to accommodate the increased sales of its current products. In five years, the new equipment will have a market value of $3.9 million if purchased today, and $6.1 million if purchased in two years. The equipment is depreciated on a seven-year MACRS schedule. The company has a tax rate of 24 percent, and the required return for the project is 13 percent. |

Two asteroids collide in space. The collision is not completely inelastic--the asteroids pull apart and continue on their way. Their masses are 8.7 X 108 kg for Asteroid A and 3.4 X 108 kg for Asteroid B. Treat Asteroid A as being initially at rest. Asteroid B, moving at high speed, strikes Asteroid A and moves from the collision at a speed of 7300 m/s in a direction 48 degrees from its original path. Meanwhile, Asteroid A moves away from the collision at a spee of 4400 m/s at an angle of 27 degrees from the original path of Asteroid B, but in the opposite direction, of course. Assume no significant amount of mass is lost in the collision (a definite oversimplification).
a) Find the initial momentum, and from it the original speed, of Asteroid B before the collision.
b) How much kinetic energy was lost in the collision?
