Physics/Expert Profile
Expertise
PLEASE READ THIS BEFORE POSTING YOUR QUESTION: While I am glad to offer HELP with problems, I refuse to SOLVE problems. There is a difference. Please do not just copy a question from a texbook or assignment. I WILL REJECT IT. I will only accept questions if, in addition to the statement of the problem, you describe in detail what you have tried so far in order to solve it, and what exactly is the problem you are encountering. In other words where/why are you stuck? I can answer general physics questions up to the level of first or second year undergraduate courses. Topics I am familiar with include: classical mechanics (kinematics, dynamics, etc.), electricity and magnetism, optics, thermodynamics, and special relativity. I may not answer questions at an advanced undergraduate or graduate levels. Also please do not expect help with algebra or arithmetic (performing numerical calculations).
Experience in the area
I have been a private physics tutor for about eight years. I also have six years of experience a teaching assistant (for both theory and lab) and occasional substitute lecturer in Physics.
Education/Credentials
B.S. in Chemical Engineering M.S. in Chemical Physics PhD in Physics.

Hello Aliya, A pointy heel makes the pressure (weight/area) on the floor higher than that of a regular heel. The result of this is that most of the women's weight is applied in a small area, which may

Hello Kristopher, You need to use F=ma. You would use W=mg if you had to calculate the weight of the truck (which you don't)... So "F" is the force, which you want to calculate. m is the mass

Hello Adam. The wavelengths that behave resonantly are the ones that fit an integer number of times in the twice the length of the room. For instance, if your room is size is 10m, the resonant wavelengths
2011-09-27 Megnetic field and its effect on protons:
Hello Devyanka, Magnets do not simply repel or attract electric charges in the way you seem to imply. They only interact with MOVING charges, changing their trajectory. This means only moving charges

Hello Mikey, No, you do not use that equation. You can only use c²=a²+b² if a and b are perpendicular. In this case they are not. Because tailwind and head wind go along the same line as the speed of
