A battery is constructed based on the oxidation of magnesium and the reduction of Cu2+. The initial concentrations of Mg2+ and Cu2+ are 1.1×10⁻⁴ M and 1.6 M , respectively, in 1.0-liter half-cells. What is the initial voltage of the battery? Answer:2.8. What is the voltage of the battery after delivering 5.0 A for 8.0 h ? How long can the battery deliver 5.0 A before going dead? Please show all step thank you

 The topic is What happened at World Com? Please describe the ethical structure and violations. For instance, was there a code of conduct? Why didn't it work? What was management like - were they ethical? What was the situation at World Com before and after the fraud? And so on. Include all relevenat information that you think is pertinent to the exploration of a company failure due to ethical violations.  Also be sure and comment on the role of the internal auditors, the CFO and the audit committee.

River Cruises is all-equity-financed with 54,000 shares. It now proposes to issue $290,000 of debt at an interest rate of 10% and to use the proceeds to repurchase 29,000 shares. Suppose that the corporate tax rate is 35%. Calculate the dollar increase in the combined after-tax income of its debtholders and equityholders if profits before interest are: (Do not round intermediate calculations.)

Increase in Cash Flow

a. $79,000

b. $104,000

c. $179,000

A resistor with 830? is connected to the plates of a charged capacitor with capacitance 4.60?F . Just before the connection is made, the charge on the capacitor is 7.00mC

Part A

What is the energy initially stored in the capacitor?

Part B

What is the electrical power dissipated in the resistor just after the connection is made?

Part C

What is the electrical power dissipated in the resistor at the instant when the energy stored in the capacitor has decreased to half the value calculated in part A?

Respond to the following statement: World War II fundamentally changed the way that Europeans understood themselves. In the second half of the 20th century, the experience of the war led people on both sides of the Iron Curtain before 1989, and throughout Europe after, to redefine what it meant to be European. By the end of the century, nations throughout the continent built an identity on a vision of unity and tolerance of everyone living in Europe. Support, refute, or refine this statement.

On a frictionless horizontal air table, puck A (with mass 0.255 kg ) is moving toward puck B (with mass 0.375 kg ), which is initially at rest. After the collision, puck A has velocity 0.117 m/s to the left, and puck B has velocity 0.650 m/s to the right.

What was the speed vAi of puck A before the collision?

Calculate ΔK, the change in the total kinetic energy of the system that occurs during the collision.

The initial pH of the KOH solution before any acid is added.

b)

The pH of the solution after 3.00 mL of HCl is added.

c)

The quantity of HCl solution required to reach the equivalence

point.

d)

The pH of the solution at the equivalence point.

e)

The pH of the solution after20.0 mL of HCl is added.

Carefully reflect on what it means to be ‘informed’ as you make decisions and judgments.

In addition, what is your perspective on the role of, or need for, authorities in terms of making good decisions (before and after our reading)?

For example, if there are medical concerns, you would consult with a doctor.

If there are concerns over the environment, you would consult with an environmental scientist or other expert in the field.What about morality?

What about becoming the kind of person you want to be?
