The formula for length contraction gives the length of an interval on a ruler moving with velocity v relative to an observer as where L is the length of the same interval on a ruler at rest with respect to the observer. By what fraction is the length of a meter stick reduced if its velocity relative to you is measured to be 87 percent of the speed of light?

Review the Medsker and McDorman article and Nixon's resignation address. How is the President treated as the accused by the courts? The Justices admit they were not "required to proceed against the president as against an ordinary individual" (United States v. Nixon 708, 715). What do you think Aristotle would have thought of this?

R& V Hotel is consistently incurring losses for the past 2 years though the sales clerk receives customer orders, raises sales invoices at a higher price and processes payments for customers. Hotel customers have contracted prices, however online trade prices automatically loaded in to the system but the Brenda clerk used to amend manually. Mr. Zakariya an internal auditor found some deficiencies, who has taken some necessary actions to cross check those invoices and employees responsibilities and suggested the management immediately to prevent from loss of customers and good will of the hotel.
Based on the above scenario:
1. How the internal audit for R and V hotel can be helpful in resolving the issues they are confronting at the moment? Justify your answer practically
2. If you were Mr. Zakariya, prepare doable audit plan that Mr. Zakariya that you can use for the company and provide recommendations on how to overcome the deficiencies cited in the case?

The cell potential of a redox reaction occurring in an electrochemical cell under any set of temperature and concentration conditions can be determined from the standard cell potential of the cell using the Nernst equation E = E° − RT nF ln Q where E is the cell potential of the cell, E° is the standard cell potential of the cell, R is the gas constant, T is the temperature in kelvin, n is the moles of electrons transferred in the reaction, and Q is the reaction quotient. Use this relationship to answer the problem below.

For the following oxidation-reduction reaction Cu2+(aq) + Ni(s) → Cu(s) + Ni2+(aq) the standard cell potential is 0.60 V. What is the actual cell potential of the cell if the temperature is 314 K, the initial Cu2+ concentration is 0.00107 M, and the initial Ni2+ concentration is 0.0183 M? (Note that the reaction involves the transfer of 2 moles of electrons, and the reaction quotient is 17.1.)

Analysis of an explosion
1. suppose that 2 carts have equal masses, m and that they both have velcro bumpers. Suppose that one of the carts will have a spring that can be compressed, thus mechanical energy stored (can be converted in kinetic). Then, you compress the spring and place both carts at the middle of the track. suppose that you release the spring.

a) is the collision elastic?

b) what is the total kinetic energy of the system before releasing the spring and how do you compare the speeds of the cart after the collision?

c) suppose that the speed of each cart is v write an expression for the total kinetic energy after the explosion, and does the model of explosion resemble an elastic or inelastic collision?

d) suppose that there are three carts each of mass m and velcro bumpers placed separately on a track. If you push one cart toward the other with a velocity of v, what is the speed of eaxh when they all move together?

Suppose you have a concentrated solution (S1) with a concentration equal to 1 M. You use their solution to make more dilute solutions S2-S6. Complete the following table, which describes the solution process. NOTE: Not all of the solutions are diluted S1; some are made from solutions that are derived from S1. The equation C1V1 = C2V2 should be used as a starting point for calculation. You can assume all volumes are additive. S2 is shown as an example.

Solution Volume (mL) of concentrated solution Volume of solvent Total Volume Dilution with respect to S1 (v/v) Concentration
S1 - - - - 1 M
S2 10 mL of S1 40 mL 50 mL 1/5 (0.20)
S3 100 mL (0.40)
S4 5 mL of S2 35 mL
S5 10 mL of S1 1/2
S6 20 mL of S1 1.0 L

Consider a Carnot-cycle heat pump with R-410a as the working fluid. Heat is rejected from the R410a at 35 oC, during which process the R-410a changes from saturated vapor to saturated liquid. The heat is transferred to the R-410a at 0 oC. The specific volume during the isothermal heat addition process at 0 oC changes from 0.00841 m3 /kg to 0.02994 m3 /kg.

a. Show the cycle on P-T, P-v, and T-v diagrams.

b. Find the quality at the beginning and at the end of the isothermal heat addition process at 0 oC.

c. Find the pressure and specific volume at the four points.

d. Find the specific heat and specific work at each process.

e. Find the net specific heat and the net specific work during the cycle.

f. Determine the COP of the cycle using heat and work.

g. Determine the COP of the cycle using temperatures.
