You place your lunch leftovers in the refrigerator. Suppose the refrigerator needs to remove 2.0090E+4 J of thermal energy from your lunch to cool it to the temperature of the inside of the refrigerator. In the meantime, this means the refrigerator produces 2.7959E+4 J of thermal energy that it expels into the kitchen as a result. What is the total work done by the compressor motor in the refrigerator? (Ignore any thermal loses due to friction in the motor.)

What is the Coefficient of Performance for the refrigerator?

Your refrigerator actually acts like a heater in your kitchen. Suppose you have a small electric space heater that has a power output of 1.2kW. How long would this heater have to run to produce the same amount of heat as the refrigerator produced while cooling your leftovers?

It takes electricity to run the motor on the refrigerator. If your cost of electricity is 13 cents per kilowatt*hour, how much does it cost (in cents - do not enter units) to cool your lunch down?

A) What should his speed be at the top of the ramp to make it to the edge of the bank? B) if his speed was half the value found in part A where would he land?  A physics professor did daredevil stunts in his spare time. His last stunt was an attempt to jump across a river on a motorcycle (the figure (Figure 1) ). The takeoff ramp was inclined at 53.0 ?, the river was 40.0 m wide, and the far bank was 15.0 m lower than the top of the ramp. The river itself was 100 m below the ramp. You can ignore air resistance.

Assume you are 25 and earn ​$31,000 per​ year, never expect to receive a​ raise, and plan to retire at age 55. If you invest 5 percent of your salary in a​ 401(k) plan returning 11 percent​ annually, and the company provides a​ $0.50 per​ $1.00 match on your contributions up to 3 percent of​ salary, what is the estimated future value of your​ 401(k) account? Once you​ retire, how much can you withdraw monthly if you want to deplete your account over 30 ​years? 

A lidar (laser radar) gun is an alternative to the standard radar gun that uses the Doppler effect to catch speeders. A lidar gun uses an infrared laser and emits a precisely times series of pulses of infrared electromagnetic waves. The time for each pulse to travel to the speeding vehicle and return to the gun is measured. In one situation a lidar gun in a stationary police car observes a difference of 1.23 10-7 s in round-trip times for two pulses that are emitted 0.440 s apart. Assuming that the speeding vehicle is approaching the police car essentially head-on, determine the speed of the vehicle.

You can buy a car that is advertised for $24,600 on the following terms: (a) pay $24,600 and receive a $4,600 rebate from the manufacturer; (b) pay $410 a month for 5 years for total payments of $24,600, implying zero percent financing.

a. Calculate the present value of the payments for option (a) if the interest rate is 1.25% per month.

b. Calculate the present value of the payments for option (b) if the interest rate is 1.25% per month. (Do not round intermediate calculations. Round your answer to 2 decimal places.)

c. Which is the better deal? Option a or Option b

For each of the scenarios described below identify 2 control procedures that could have prevented the problem and explain why each of the controls would have helped.

a) you manage a sales firm, and you give laptops to all salespeople. salespeople can input orders and submit them electronically while on the road. you have had a few problems with this system. In one instance an order for 5 pcs was input b the salesperson as 500 pcs. in another case, the salesperson failed to input a delivery address.

b) a computer programmer from the payroll department created a fake employee number and entered this employee in the payroll database. she then prepared paychecks for this fake employee using the payroll systems and sent them to her own po box address.

c) two brothers have lived in Texas all of their lives. joe worked for a local retailer in the account payable department, and John owned the local hardware store. the brothers created several dummy companies that sold fictitious merchandise to the retailer. joe had the retailer pay for this merchandise, and then he wrote off the missing goods as damaged inventory.

By what factor must your blood pressure increase to compensate for a 4 % narrowing in your blood vessels? (The pressure difference across your blood vessels is essentially equal to your blood pressure.) I am learning the bernoullis equation and also the poiseuille law. But can't figure out how to do this with only knowing a percent. I need each step please.

An investor company owns 30% of the common stock of an investee company. The investor has significant influence over the investee, and acquired its equity interest in the investee on January 1, 2018 for $525,000. On the date of acquisition, the investee’s stockholders equity was $1,500,000, and the fair values of the investee’s individual net assets were equal to their reported book values. During the year ended December 31, 2018, the investee reported net income of $50,000 and dividends of $10,000. During the year ended December 31, 2019, the investee reported net income of $60,000 and dividends of $15,000. The investor routinely sells inventory to the investee at a 25% profit margin. At December 31, 2018 and 2019, the investee held inventories purchased from the investor for $30,000 and $40,000, respectively. (At the end of each period, all of these inventories are sold by the investee to unaffiliated companies in the next period.)

What is the balance in the Equity Investment account on December 31, 2019?

Select one:

a. $ 525,000

b. $ 547,500

c. $ 550,500
