Sarah attempts to do the popular physics trick of swinging a pail of water around in a vertical circle fast enough so the water doesn't spill out when the pail is upside down. if her arm is 0.417 meters long, what is the minimum speed with which she can swing the pail so the water does not spill out at the top of the path? (assume that you may neglect the length of the pail).

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.
