A refrigerator receives 500W of electrical power to the compressor driving the cycle flow of R134a. The refrigerator operates with a condensing temperature of 40$^{\circ} \mathrm{C}$ and a low temperature of –5$^{\circ} \mathrm{C}$. Find the COP for the cycle and its cooling capacity.

Place in order the electrical events of the heart. In the list below, number the events as they normally occur in the heart. Start with 1 for the first event, through 5 for the last event. _________ AV bundle _________ SA node _________ Purkinje fibers _________ AV node _________ bundle branches

The average amount of life insurance per household in the United States, according to data from the American Institute of Insurance, is $165,000. With a standard deviation of$40,000, this distribution fits the normal distribution. What is the likelihood of selecting a sample with a mean of more than $155,000?

Electrical current is passed through a resistor immersed in a liquid in an adiabatic container. The temperature of the liquid is varied by $1^\circ C$. The system consists solely of the liquid. Does heat or work flow across the boundary between the system and surroundings? Justify your answer.

How do life insurance companies and pension funds differ in the way they serve their clients?

A house is heated by a $24.0-\mathrm{kW}$ electric furnace that uses resistance heating. The rate for electrical energy is $\$ 0.080 / \mathrm{kWh}$. If the heating bill for January is $\$ 200$, how long must the furnace have been running on an average January day?

It is not a good idea to stick the ends of a metal paper clip into the two rectangular slots of a household electrical wall outlet in the United States. Explain why by estimating the current that a paper clip would carry until either the fuse blows or the breaker trips.

Solve the indicated equations graphically. Two electrical resistors in parallel have a combined resistance $R_T$ given by $R_T =\frac{R_1R_2}{R_1 + R_2}$. If $R_2 = R_1 + 2.0$, express $R_T$ as a function of $R_1$ and find $R_1$ if $R_T = 6.0\;\Omega$.

The average U.S. household has $\$ 235,600$ in life insurance. A local insurance agent would like to see how households in his city compare to the national average, and selects a simple random sample of 30 households from the city. For households in the sample, the average amount of life insurance is $\bar{x}=\$ 245,800$, with $s=\$ 25,500$.

b. For the significance level used in part (a), construct the appropriate confidence interval and verify the conclusion reached in part (a).

The electrical resistance R of a certain resistor as a function of the temperature T (in degrees C) is given by $R=10.0+0.01T+0.001T^2$. If a given temperature T is decreased by 10 degrees C, what is the value of R for the decreased temperature as a function of T?

In an L-R-C series circuit, $R=300 \Omega, X_{C}=300 \Omega$, and $X_{L}=500 \Omega$. The average electrical power consumed in the resistor is 60.0 W. (a) What is the power factor of the circuit? (b) What is the rms voltage of the source?

In this exercise, express the indicated number as a power.

An ice machine is to convert $10^{\circ} \mathrm{C}$ water to $0^{\circ} \mathrm{C}$ ice. If the machine has a COP of 2.0 and consumes electrical power at a rate of 1.0 kW, how much ice can it make in 1.0 h?
