Net revenues at an older manufacturing plant will be $2 million this year. The net revenue will decrease by 15% per year for 5 years, when the assembly plant will be closed (at the end of year 6). If the firm's interest rate is 10%, calculate the PW of the revenue stream. Use excel functions and a table.

A resistor of resistance R and a capacitor of capacitance C are connected in series to an EMF of voltage E. A switch is set to the open position and the capacitor is initially uncharged. The switch is then closed. Show that when the capacitor charges that half of the energy drawn from the EMF is dissipated in the resistor and that half of the energy is stored in the capacitor.

how do I write this function to check if it is close?

below is checking if the function is open. I want to write another if then statement to check when that function is closed and when the queue is empty. You can use any variables or declaration as a example to show me how it is done.

A spherical satellite of radius 4.8 m and mass M = 210 kg is originally moving with velocity _satellite,i = < 2800, 0, 0 > m/s, and is originally rotating with an angular speed ω₁ = 2 radians/second, in the direction shown in the diagram. A small piece of space junk of mass m = 3.9 kg is initially moving toward the satellite with velocity _junk,i = < -2600, 0, 0 > m/s. The space junk hits the edge of the satellite at location C as shown in the diagram, and moves off with a new velocity _junk,f = < -1100, 510, 0 > m/s. Both before and after the collision, the rotation of the space junk is negligible.

MOMENTUM
After the collision, what is the final momentum of the satellite?
_satellite,f = _____ kg · m/s

What is the final velocity of the satellite?
_satellite,f = _____ m/s

ANGULAR MOMENTUM
Assuming the density of the satellite is uniform throughout, what is the moment of inertia of the satellite? (The moment of inertia of a uniform-density sphere is (2/5)MR².)

I = _____kg · m²

What is the initial rotational angular momentum of the satellite, around location D (its center of mass)? (Be sure your signs are correct).
_satellite,i = _____kg · m²/s

An instant before the collision, when the space junk is almost at location C, what is the translational angular momentum of the space junk about location D?

_junk,i = ____ kg · m²/s

An instant after the collision, when the space junk is just slightly beyond location C, what is the translational angular momentum of the space junk about location D?

_junk,f = _____ kg · m²/s

At the same instant after the collision, what is the rotational angular momentum of the satellite?

_satellite,f = ______kg · m²/s

What is the new angular speed of the satellite?
= ____ radians/s

In what direction is the satellite now rotating?

a. counterclockwise b.clockwise c.not rotating

ENERGY
Consider a system consisting of both objects (space junk and satellite).

Before the collision, what was the total kinetic energy (translational + rotational) of the system?

K_i = ___ joules

After the collision, what is the total kinetic energy of the system?

K_f = ___ joules

What was the rise in thermal energy for the space junk and satellite combined? (Your answer will be judged correct if it is consistent with earlier work, even if there were mistakes in the earlier work -- "propagation of errors".)

ΔE_thermal = ____ joules

Problem 17-6AA Income statement computations and format LO A2

[The following information applies to the questions displayed below.]

Selected account balances from the adjusted trial balance for Olinda Corporation as of its calendar year-end December 31, 2017, follow.

Problem 17-6 Part 1

Required:
1. Assume that the company’s income tax rate is 30% for all items. Compute the tax effects and after-tax amounts of the three items labeled pretax.

Problem 17-6 Part 2

2a. What is the amount of income from continuing operations before income taxes?
2b. What is the amount of the income taxes expense?
2c. What is the amount of income from continuing operations?

What is the amount of income from continuing operations before income taxes?

Analyzing and Interpreting Income Components and Disclosures
The income statement for Xerox Corporation follows.

(a) Which of the following best describes how sales, service, and finance revenues should be recognized?

Sales, service, and finance revenues should be recognized when cash is collected.

Sales, service, and finance revenues are recognized when earned, regardless of when cash is collected.

Sales and service revenues are recognized when the sale is made or the service is performed. Finance revenues are recognized when the loan is initially made.

Sales and finance revenues are generally recognized when the sale is made and the loan is extended to the customer. Service revenues are deferred until the end of the service contract, at which time they are recognized in full.

Mark 1.00 out of 1.00

(b) Compute the relative size of Sales revenue (total) and of revenue from Service, outsourcing and rentals. Hint: Scale each type of revenue by Total revenue.

Round percentage answers to one decimal place (ex: 0.2345 = 23.5%).

(c) Which of the following best summarizes our conclusion about the potential use of "other expense" accounts to obscure actual financial performance.

We need not worry about the reporting of "other expense" accounts because the threshold for materiality is so low that the majority of items are not classified in such accounts.

Companies are not allowed to commingle income increasing and income decreasing accounts as this would reduce the usefulness of such an account.

Companies are not required to separately disclose revenue and expense items unless they are deemed to be material. Such aggregation may reduce the usefulness of income statements.

GAAP does not permit the use of "other expense" accounts because they are not specific enough.

need help solving this .. thank you
