A mass spectrometer is an important tool in the study of air pollution. However, one of the difficulties faced by scientists is that carbon monoxide molecules (CO), which are major contributors to air pollution, have very nearly the same mass as harmless nitrogen molecules...
Hi, I have conducted an experiment to calculate the rate of change of water as it passes through 1cm levels (10 down to 0) across a uniform cross section of a juice bottle (rectangular prism shaped). I was wondering how I could verify/prove that the area under the curve is equal to the initial...
I am doing an experiment involving determing the angular velocity of a homopolar motor (simple set up of the screw, battery, magnet and copper wire) and was wondering what the limiting factor on the speed would be. One website suggests that this might be back emf.
