Explain in your own words the three ideas of sample size. What are the differences between that and a census?

1. Examine the results of Part I. What is the relationship between the three voltage readings: V1, V2, and VTOT?
2. From the equivalent resistance readings for the series circuits, can you come up with a rule for the equivalent resistance (Req) of a series circuit with two resistors?
3. Examine the results of Part II. What do you notice about the relationship between the three voltage readings V1, V2, and VTOT in parallel circuits?
4. From the equivalent resistance readings for the parallel circuits, can you come up with a rule for the equivalent resistance (Req) of a parallel circuit with two resistors?
5. What did you discover about the current flow in a series circuit in Part III?
6. What did you discover about the current flow in a Parallel circuit in Part III?
7. If the two measured currents in your parallel circuit were not the same, which resistor had the larger current going through it? Why?

Three long, straight wires are seen end-on in the figure below. The distance between the wires is r = 0.260 m. Wires A and B carry current IA = IB = 1.66 A, and wire C carries current IC = 3.18 A. Assume (for example) the only forces exerted on wire A are due to wires B and C. Find the force per unit length exerted on the following. (Express your answers in vector form.)

(a) wire A
f_A = N/m

(b) wire B
f_B = N/m

Please answer these three questions:

1. What are the differences in spectra between molecular and atomic absorption? Explain these differences using the types of transitions.

2. UV-Vis instruments used to measure molecular absorption typically have a broad wavelength light source while atomic absorption instruments use a light source that produces very narrow bands of light. Both are typically in the same UV-Vis wavelength range. Why don’t they use the same source?

3. Alkenes such as n-hexane are used as solvents in UV spectroscopy. The energy difference for the σ → σ* transition is 886 kJ/mol. What wavelength does hexane absorb? Why is n-hexane a good choice as a solvent for UV/Vis spectroscopy?

Discuss why it is important to have a balance between the three elements of behavioral control—(1) building a strong and effective culture, (2) motivating with rewards and incentives, and (3) setting boundaries and constraints.

1. An investor needs to choose between three bonds. The first bond will give the investor five equal payments of P1, paid monthly and beginning in one month. The second bond will give the investor three equal payments of P2, paid every second month and beginning now. The third bond is a coupon bond with face value F, coupon rate c per month, maturity in five months, and monthly payments beginning in one month. The return over a one month period is R and stays at this rate for the life of all three bonds.

(a) Write a formula in terms of P1 and R which gives the present value of the first bond (at time t = 0).

(b) Write a formula in terms of P2 and R which gives the present value of the second bond (at time t = 0).

(c) Write a formula in terms of F, c and R which gives the present value of the third bond (at time t = 0).

(d) Write a formula for the present value of the second bond which is valid for any time t between t = 0 and t = 4 months. Hint: write this formula in terms of three zero-coupon bonds P(t, Ti) with i = 1, 2, 3 and T1 = 0, T2 = 2 months and T3 = 4 months.

(e) For P1 = $82 , P2 = $100 , F = $200 , c = 8% per month , and R = 1.04 , which bond is the best choice for the investor? In other words, which bond has the larger present value (at time t = 0)?
