To heat water to 101 degrees C at 1 atmosphere?
Is there any case when this is possible? Even off the wall lab stuff will suffice.
What if water isn't completely pure, like most tap water here in the states? My teacher says it isn't possible but any caveat to prove him wrong would be...
Exactly how I read it. The center of mass is undergoing no translational motion, so I dropped the (.5)(M)(velocity squared) from the KE equation. So if I was to substitute in the value of zero, the whole thing would be zero and if that happens my head will explode haha.
I guess I just imagine...
I see what you did there, but I would be left with a linear velocity value in the energy equation which I still cannot find without a radius. (This assumes I understand your response haha).
Substitution would lead to a KE equation as follows : W = (.5)(.5)(M)(r squared)[(v / r) squared]...
