Mark decided that participants in this study will not be at risk, and therefore, he didn't bother the IRB with his proposal. His study investigates the number of discomfort people is willing to put up with in order to earn a large sum of money. He recruits students by posting ads about a "contest in which you can earn $1000." Everyone who shows up is told that they must do whatever he tells them to do for the next several hours and that the last person to comply will earn the money. He then makes the participants eat disgusting food combinations, rub permanent markers on their own faces, and mail insulting messages to their professors. After two hours he stops the "contest," informs everyone that it was actually an experiment, and explains that there is no prize money. Before participants leave, he gets them to sign an informed consent form to acknowledge that they "were free to leave at any time."

Consider a production line with five stations. station 1 can produce a unit in 9 minutes. station 2 can produce a unit in 10 minutes. station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. station 4 can produce a unit in 5 minutes. station 5 can produce a unit in 8 minutes. which station is the bottleneck station?

Acharged particle moves in a circular path in a uniform magnetic field. which of the following would increase the period of the particle's motion? check all that apply. increasing its chargeincreasing its massincreasing the field strengthincreasing its speed

Use the library or internet to research each planet. make a chart comparing the following: approximate surface temperature relative surface gravity compared to earth atmospheric gases water in any form: solid, gas, or liquid when you have completed your chart, use the information you have collected to answer the following questions: which is the hottest planet? which is the coldest planet? which planet's temperature is closest to that of earth? (note: water boils at 100°c/212°f. water freezes at 0°c/32°f) which planet has the greatest gravitational attraction? which planet has the least gravitational attraction? which planet's gravitational pull is closest to that of earth? do any of the planets have oxygen in their atmosphere? which planet's atmosphere most resembles that of earth? do any of the planets have flowing water? which planet's water resources (solid, gas, or liquid) might be close to the amount on earth? which planet most resembles earth in terms of all of the factors: temperature, gravity, atmosphere, and water? if earth became an uninhabitable planet, which planet do you think would be the next best to live on? explain your answer.
