The angular momentum of a freely rotating disk around its center is ldisk. you toss a heavy block horizontally onto the disk along the direction shown. friction acts between the disk and the block so that eventually the block is at rest on the disk and rotates with it. we will choose the initial angular momentum of the disk to be positive. 1) what is the total, the magnitude of the angular momentum of the disk-block system

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.
