I'm working Ksp problems comparing pure water solutions w/ those with an ion already present in solution. Example: AgCl and NaCl both in solution.
The pure water Ksp for AgCl is given as 1.77x10^-10. The question is what the Ksp would be with .01M of Cl- already present. After working the...
Simon Bridge! THANK YOU. That makes so much more sense knowing that the terminal velocity means that the acceleration has dropped to 0. It was that one little piece that made the difference. I got it now.
I was working on problems for the MCAT and came across this below. After a few minutes working, I had couldn't come up with the solution. Usually the answer clears up any questions I have, but I'm having trouble figuring out how the force due to gravity matches the force of friction. I thought...
This may be a pretty dumb question, but how is it that as the exponent value of e decreases, the rate k increases? This seems counter-intuitive, and when I enter values for e into my calculator and compare them, the higher exponents (e.g. 50 vs. 20) give higher results.
I'm dealing with this problem for an MCAT review:
Following beta-emission by a neutral atom at rest, the respective linear momentums of the beta(-) particle and the resulting atom are shown below. (see attachment for message)
It wasn't too difficult to see that an extra force is in play, and...
This is a conceptual problem that I'm sure is pretty common. How can kinetic energy (1/2mv^2) be a scalar quantity when it includes a vector quantity like velocity?
I may have made a mistake in calculating, but I just finished lab homework where my calculated momentum was different before and after an inelastic collsion. Is it possible that momentum was lost in the vibration of the impact or something?
The experiment placed two gliders on a level air...
