Adisk of radius r is attached to a rod of length l2, and it rotates about it with angular velocity @ (as shown). the rod pivots about an arm of length l1, with angle o. this arm is attached to a vertical shaft that is rotating with the constant angular velocity of q. find (a) the angular velocity and (b) angular acceleration of the disk, and (c) the velocity and (d) acceleration of the center of the disk.

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.
