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?

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
