The circle represents a reversible engine. During some integral number of
complete cycles the engine absorbs 1200 J from the reservoir at 400 K and performs 200 J
of mechanical work. (a) Find the quantities of heat exchanged with the other reservoirs,
and state whether the reservoir gives up or absorbs heat. (b) Find the change in entropy
of each reservoir, (c) What is the change in entropy of the universe ?​

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.
