Deriving cash flows for asset disposition. Custom Machining Company (CMC) purchased a made-to-order machine tool for grinding machine parts. The machine costs $160,000, and CMC installed it yesterday. Today, a vendor offers a machine tool that will do exactly the same work but costs only $80,000. Assume that the cost of capital is 12 percent, that both machines will last five years, that CMC will depreciate both machines on a straight-line basis for tax purposes with no salvage value, that the income tax rate is and will continue to be 40 percent, and that CMC earns sufficient income that it can offset any loss from disposing of or depreciating the ‘‘old’’ machine against other taxable income. How much, at a minimum, must the ‘‘old’’ machine fetch upon resale at this time to make purchasing the new machine worthwhile?

I have asked the question before, but I do not understand how depreciation * tax rate (for example $16,000* .4 = $64,000, instead of $4,000 or $32,000* .4= $128,000, instead of $8,000?).

A steam pipe is covered with 1.50-cm thick insulating material of thermal conductivity of 0.200 cal/cm · °C · s. How much energy is lost every second when the steam is at 240°C and the surrounding air is at 20.0°C? The pipe has a circumference of 800 cm and a length of 50.0 m. Neglect losses through the ends of the pipe.

Suppose a bridge has 10 toll booths in the east-bound lane: four are only for E-Z Pass holders, two are only for exact change, one takes only tokens, and the remainder are manned by toll collectors who accept only cash. During heavy-traffic hours it is difficult to see the signs indicating the type of toll booth. Suppose a driver selects a toll booth randomly.

• a. What is the probability that an exact-change toll booth is selected?

• b. What is the probability that a manual-collection toll booth or the token toll booth is selected?

• c. What is the probability that an E-Z Pass toll booth is not selected?

• d. Suppose the driver has only tokens. What is the probability of selecting the appropriate toll booth?

Illustrate with a diagram how basic TCP Windowing works.

A proton and an alpha particle (q=+2e,m=4u) are fired directly toward each other from far away, each with an initial speed

of 0.014 c .

Part A

What is their distance of closest approach, as measured between their centers?

Express your answer to two significant figures and include the appropriate units

How can discuss the subject (the nearly free electron approximation)? and tight-binding approximation?

Suppose that the average U.S. household uses 13600 kWh (kilowatt-hours) of energy in a year. If the average rate of energy consumed by the house was instead diverted to lift a 2350 kg car 11.3 m into the air, how long would it take?

Using the same rate of energy consumption, how long would it take to lift a loaded 747, with a mass of 4.10 × 105 kg, to a cruising altitude of 9.67 km?

A 19.0-kg child on a 4.00-m-long swing is released from rest when the ropes of the swing make an angle of 35.0° with the vertical.

(a) Neglecting friction, find the child's speed at the lowest position.
m/s

(b) If the actual speed of the child at the lowest position is 3.30 m/s, what is the mechanical energy lost due to friction?
J

Q) Create a python functions that rotates the elements of a list by one position. Consider a function rotate(a_list, direction) that takes as arguments the list to rotate, and the direction (left or right) of rotation. Rotate the list in place.

Q) Choice of appropriate data structure is an important step in designing algorithms. Suppose a text file contains student records on each line and each record is of the format: Name of Student, Student ID, GPA. Now consider reading that le to create a list of lists, a list of tuples or a tuple of tuples.
(a) If you want to create a report using the data, what data structure would you use?

(b) If you want to modify the name, id or GPA, what data structure would you use?

[13] Write the equilibrium mass balance expressions for the following equilibrium in terms of (a) KC and (b) KP.
4HCl(aq) + MnO2(s) ? Cl2(g) + 2H2O(l) + MnCl2(aq)

[14] At 700 K the rate constant for the reaction 2NO + O2 ? 2NO2 is 5.73

The dollar cost of debt for Coval​ Consulting, a U.S. research​ firm, is 7.3%.

The firm faces a tax rate of 37% on all​ income, no matter where it is earned. Managers in the firm need to know its yen cost of debt because they are considering a new bond issue in Tokyo to raise money for a new investment there. The​ risk-free interest rates on dollars and yen are

r Subscript $ Baseline equals r$=5%

and r Subscript yen Baseline equals r¥=1.4%

respectively. Coval Consulting is willing to assume that capital markets are internationally integrated and that its free cash flows are uncorrelated with the​ yen-dollar spot rate. What is Coval​ Consulting's after-tax cost of debt in​ yen? ​(Hint: Start by finding the​ after-tax cost of debt in dollars and then finding the yen​ equivalent.)

The​ after-tax cost of debt in dollars is _____________%. (Round to two decimal​ places.)

Malonic acid (FW = 104.06) is a diprotic acid of the form CH2(COOH)2, with pKa1 = 2.847
and pKa2 = 5.696. Assume all solutions are ideal.
(a) If 15.000 g of malonic acid is added to 100 mL of pure water, what will the pH of the
solution be?
(b) You add 18 mL of 5 M NaOH to the solution in part (a). What will the new pH be?
(c) You then add 5.000 g of sodium malonate (Na2CH2(COO), FW = 148.025). What will
the new pH be?
