Atrial evaluated the fever-inducing effects of three substances. study subjects were adults seen in an emergency room with diagnoses of the flu and body temperatures between 100.0 and 100.9ºf. the three treatments (aspirin, ibuprofen and acetaminophen) were assigned randomly to study subjects. body temperatures were reevaluated 2 hours after administration of treatments. the below table lists the data. table: decreases in body temperature (degrees fahrenheit)group 1 (aspirin)0.951.481.331.28group 2 (ibuprofen)0.390.441.312.481.39grou p 3 (acetaminophen)0.191.020.070.010.62 -0.39complete an anova for the above. what do you conclude?

Most short-period comets do not have randomly oriented orbits because

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a

You are still fascinated by the process of inkjet printing, as described in the opening storyline for this chapter. you convince your father to take you to his manufacturing facility to see the machines that print expiration dates on eggs. you strike up a conversation with the technician operating the machine. he tells you that the ink drops are created using a piezoelectric crystal, acoustic waves, and the plateau-rayleigh instability, which creates uniform drops of mass m = 1.25 ✕ 10−8 g. while you don't understand the fancy words, you do recognize mass! the technician also tells you that the drops are charged to a controllable value of q and then projected vertically downward between parallel deflecting plates at a constant terminal speed of 20.0 m/s. the plates are ℓ = 2.15 cm long and have a uniform electric field of magnitude e = 6.40 ✕ 104 n/c between them. noting your interest in the process, the technician asks you, "if the position on the egg at which the drop is to be deposited requires that its deflection at the bottom end of the plates be 0.17 mm, what is the required charge on the drop (in c)? " you quickly get to work to find the answer. (neglect the force of gravity.)
