The Quest For Perpetual Motion It has been a tenet of physics that it is not possible to build a perpetual motion machine in a closed or isolated system. This fact has not stopped people from claiming to build such a machine. Explain why a perpetual motion machine violates the principles of thermodynamics. Do some research and provide an example of a supposed perpetual motion machine. Explain the machine in detail and why it does not exhibit perpetual motion.

1. Discuss the functional anatomy of the hip.
   

2. Discuss the normal Angle of Inclination of the adult hip and potential compensation patterns seen with excessive varus or valgus angles.
   

3. Discuss the normal Femoral Torsion Angle of the adult hip and potential compensation patterns seen with excessive anterior or posterior angulation.
   

4. Discuss 3 planes of closed chain hip osteokinematics.
   

5. Discuss the osteokinematics of contra-directional lumbopelvic movements in the sagittal and frontal planes.
   

Suppose the investment is very sensitive to the interest rate.That is, the function I(r), used to derive the IS curve, is very steep (that is, when we graph it with r on the vertical axis, it is very flat, almost horizontal). Graphically derive the IS curve in the closed economy. What can you say about the steepness IS curve? In this context, which policy do you think is likely to be more effective? Fiscal policy or monetary policy?

A project will not produce any cash flows for two years. Starting in the third year, it will produce annual cash flows of $11,900 a year for two years. The project initially costs $43,600. In Year 6, the project will be closed and as a result should produce a final cash inflow of $50,500. What is the net present value of this project if the required rate of return is 8.7 percent?

Ex. 840. A proportional controller, Kp, is desired for the plant
1/( (s) (s+ 8) (s+11) ).  Design the unity feedback system so that the
dominant poles indicate a closed loop step response with a 36% overshoot.
What is Kp, zeta, wn, wd, Ts, Tp, the velocity constant (Kv) and the resulting
SS error for a ramp input, and the gain, Kp, for marginal stability. ans:9

Evaluate the surface integral

F · dS

for the given vector field F and the oriented surface S. In other words, find the flux of F across S. For closed surfaces, use the positive (outward) orientation.

F(x, y, z) = x i + y j + z⁴ k

S is the part of the cone z =

beneath the plane

z = 1

with downward orientation

At the balance sheet date, Clarkson Company held title to goods in transit amounting to $214,000. This amount was omitted from the purchases figure for the year and also from the ending inventory. What is the effect of this omission on the net income for the year as calculated when the books are closed? What is the effect on the company’s financial position as shown in its balance sheet? Is materiality a factor in determining whether an adjustment for this item should be made?

part1. A double-blind design is important in an experiment because there is a natural tendency for subjects in an experiment to want to please the researcher.

a. True

b. False

part 2.

Sampling error concerns natural variation between samples, and is always present.

a. True

b. False

part 3. Sampling error can only be eliminated when conducting a questionnaire of students and every question is a closed question.

a. True

b. False

A 3.10-N metal bar, 2.00 m long and having a resistance of 10.0 Ω, rests horizontally on conducting wires connecting it to the circuit shown in the figure (Figure 1) . The bar is in a uniform, horizontal, 1.40-T magnetic field and is not attached to the wires in the circuit.

What is the magnitude of the acceleration of the bar just after the switch S is closed?

The Down Towner is considering a project with a life of 4 years that will require $164,800 for fixed assets and $42,400 for net working capital. The fixed assets will be depreciated using the Year 2018 bonus depreciation method. At the end of the project, the fixed assets can be sold for $37,500 cash and the net working capital will return to its original level. The project is expected to generate annual sales of $195,000 and costs of $117,500. The tax rate is 24 percent and the required rate of return is 13 percent. What is the project's net present value?
