Abottle contains a label stating that it contains pills with 500 mg of vitamin c, and another bottle contains a label stating that it contains pills with 325 mg of aspirin. when testing claims about the mean contents of the pills, which would have more serious implications: rejection of the vitamin c claim or rejection of the aspirin claim? considering only a type i error and using the same sample size, is it wise to use the same significance level for hypothesis tests about the mean amount of vitamin c and the mean amount of aspirin?

Your friend offers to show you an intrusive igneous rock. which of the following would you expect to see?

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.

2pos suppose an object in free fall is dropped from a building. its starting velocity is 0 m/s. ignoring the effects of air resistance, what is the speed (in m/s) of the object after falling 3 seconds? give your answer as a positive decimal without units. answer here
