Thanks guys. I can't believe I didn't know that "g" meant gravity.

What is a "g"? What is the electric field strength at a paoint in space where a protone (m=1.67x10^-27 kg) experiences an acceleration of 1 million "g's"? My only question is: What is a "g"?

Homework Statement A guitar string produces 4 beat/s when sounded with a 350-Hz tuning fork and 9 beat/s when sounded with a 355-Hz fork. What is the vibrational frequency of the string? Explain your reasoning. Homework Equations f=v//\ The Attempt at a Solution I'm not quite sure...

AWESOME! :biggrin: Thanks for your help guys.

So, you're saying that there is no work being done by the cord since F*D=FDcos@= 0 ? My bad. :redface: F = m*a F=m*(v^2/r) F = (0.200kg)*((3.7m/s)^2)/(0.500m)) F = 5.476 Right?

Are you referring to this acceleration? http://img256.imageshack.us/img256/3849/u6l1e2ir5.gif ------------------------------------ [SIZE="5"]a. If I use W=mad, I still do not know the acceleration or velocity since it is not given in part a. Am I using the right forumula...

How did I double post? [SIZE="5"]Some thoughts. [SIZE="5"]- Since part a asks for "work", I thought I'd try the work forumula. W=Fd. I then substituted F=ma into the forumula and got W=mad. I plugged in the variables and got W=(0.200kg)(0.500m)a. Since the ball is not accelerating...

Does anyone know where I can find some comic strips about electricity and magnetism.

I am currently struggling in AP Physics B at school and find the textbook issued to me by the school (College Physics by Serway and Faughn Fifth Edition) a bit difficult to comprehend. I do not want to fail the class or the AP test and was wondering if there were any good, easy to understand AP...

The eye of a hurricane passes over Grand Bahama Island. It is moving in a direction of 60.0 (degrees) north of west with a speed of 41.0 km/h. 3 hours later, the course of the hurricane suddenly shifts due north, and its speed slows to 25.0 km/h. How far from Grand Bahama is the hurricane 4.50 h...

I see.. What does y represent? EDIT: nvm, I found it in the book.

A ball is thrown vertically upward with a speed of 25.0 m/s. (a) How high does it rise? (b) How long does it take to reach its highest point. (c) How long does it take to hit the ground after it reaches its highest point? (d) What is its speed when it returns to the level from which it started...

Wow, its so simple. Thanks for your help, BishopUser.
