this might be a very stupid question :) I always hear nurses complaining about how hard is nursing school, and always heard docs comlaining about how difficult med school is, so besides the fact that nursing school lasts for 4 year (sorry if I'm wrong, but what I'm trying to say is that it takes shorter to become a nurse than to become a doctor) and becoming a doc takes up to 11 year, how much harder is med school than nursing school? I know they're totally different, but I just mean the level of difficulty.

Thanks in advance!!!!!

A reaction between substances A and B is represented stoichiometrically by
A + B → C
The rate of the reaction depends only on the concentration of B. A plot of [B]−1 vs time is found to be linear with a slope of 0.0962 L/mol-s. If the intial concentration of B is 0.26 mol/L. What is the concentration of B after 40 seconds ?

I have to do a balloon powered race car for my science class and I need some ideas of what materials I can use that would make it go fast, but stay on the ground.

Rules:
* The car must be powered by 1 balloon
* You can build the car out of anything
* It must have at least three wheels. Wheels are defined
as anything that is round and goes around.
* The wheels CAN NOT be wheels from a toy car. They
must be made out of something that was not originally
meant to be usedas wheels.
* The car may not leave the ground


Thank you so much for anyone that gives me ideas. I really appreciate it!

What is the "force carrier" of a magnetic field? Is it photons? I know that the field is generated by the aligned electrons in a permanent magnet, or by a moving charge, but what is the magic stuff flying through space around whatever is generating the field that actually makes up the B field?

What different Titanium alloys are there and what advantages do they hold over pure Titanium?

This is part of an sports engineering project (Tennis Racket) that I am doing.

How about:
greater vibrational dispersion?

or greater biocompatability?

anything to do with the oxide layer created being less?

I need to know as many reasons as possible please, and thank you for your help on this occasion.
