How do you know an organism is a heterotroph? Name three heterotrophs.

For the foot-operated air pump shown, use the instantaneous center method to graphically determine the rate of cylinder compression as the foot pedal assembly rotates counterclockwise at a rate of $0.75 \mathrm{rad} / \mathrm{s}$.

Identify and state the significance of each of the following trade-related entities: (a) the WTO; (b) the EU; (c) the eurozone; and {d) NAETA.

Calculate the heat of atomization (see the previous problem) of $\mathrm{C}_2 \mathrm{H}_3 \mathrm{Cl}$, using the average bond energies as we discussed earlier.

a. What are the three main types of stress in rock? b. How does tension change the shape of Earth's crust? c. Compare the way that compression affects the crust to the way that tension affects the crust.

(a) The number of kilocalories in food is determined by calorimetry techniques in which the food is burned and the amount of heat transfer is measured. How many kilocalories per gram are there in a 5.00-g peanut if the energy from burning it is transferred to 0.500 kg of water held in a 0.100-kg aluminum cup, causing a $54.9 - ^ { \circ } \mathrm { C }$ temperature increase? Assume the process takes place in an ideal calorimeter, in other words a perfectly insulated container. (b) Compare your answer to the following labeling information found on a package of dry roasted peanuts: a serving of 33 g contains 200 calories. Comment on whether the values are consistent.

$$.001$$

An air-standard dual cycle has a compression ratio of 9. At the beginning of compression, $P_1= 100 kPa, T_1 = 300 K.$ The heat addition per unit mass of air is 1400 kJ/kg, with two-thirds added at constant volume and one-third added at constant pressure. Determine a. the temperatures at the end of each heat addition process, in K. b. the net work of the cycle per unit mass of air, in kJ/kg. c. the thermal efficiency. d. the mean effective pressure, in kPa.

Which of the words sets below describes a vulture eating a dead rabbit?

a. heterotroph, scavenger

b. parasite, predator

c. herbivore, mutualism

d. competitor, commensalisms

State the null hypothesis, $H_0$, and the alternative hypothesis, $H_a$, to be tested. A statistical test is designed to show that the mean $\mu$ is greater than 3 .

Complete the following statement: The smaller the p -value associated with a test of hypothesis, the stronger is the support for the ____ hypothesis. Explain your answer.

A company manufactures five sizes of screwdrivers. Ordering costs and carrying costs are not known, but it is known that they are the same for each size. At present, each size is produced four times per year. If the demand for each size is as follows, calculate order quantities to minimize inventories and maintain the same total number of runs. Calculate the old and new average inventories. Is there any change in the number of orders per year?

Define the term hypothesis.
