May someone please explain what were some problems with the Bohr model of the atom. I found a few things on Wikipedia, but I being a beginner in the Physics curriculum do not fully understand how it all ties together. If there is a link to this topic in the forums, please do tell. Thanks.
Here is the problem i need help with.
I run up a down escalator at a speed of 2 m/s while the escalator is moving at a rate of 0.75 m/s. What is the resultant velocity?
Of course, I do not need help getting the resultant velocity. I just need help drawing the vector diagram that can help...
