a cosmic ray creates a muon in the earth's upper atmosphere that travels towards the earth at 0.998c. the muon exists for 3.16 ms when measured by an observer on earth. during its lifetime: a) how far does an observer on earth say the muon has traveled? b) find the lifetime of the muon as measured by an observer at rest with respect to the muon. c) how far does the muon say that it has traveled relative to earth?

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
