ok, I did what you said and got the current as 91.8A, but is this right? I found the horizontal force to be 1.29 and the length between the wires to be .0259 meters, then i used the equation, F/L= (permeability of freespace)(I^2)/ 2(pi)r, and I took the force and multipled it by the .050 kg/m...

Hi, I have a problem here that I'm having trouble with, I attempted to do it by using equations dealing with magnetic fields and electric fields, but then i had to consider the tensions of the strings and the components and became lost. Can anyone help me? Thanks in advance, Here is the...

I'm on static/kinetic friction, tension force, and Equilibrium applications of Newton's Laws of motion. I have many homework problems that baffles my mind and need serious help understanding them. So, any help will be appreciated. 1] 'A large cube (mass= 25 kg) being accelerated across a...

anyone please help me

Need a setup for a friction problem I know the concept of this problem but i don't know how to set it up... 'A large cube (mass= 25 kg) being accelerated across a horizontal frictionless surface by a horizontal force P. A small cube (mass= 4.0 kg) is in contact with the front surface of the...

Hmm... I think I'll stick with this book but I need some help with concepts, since I don't want to create another topic I'll post it here. Why is gravity sometimes positive and sometimes negative? because in the book I see an object fall down and its negative then in another example an object is...

I'm currently in 11th grade, but decided to get physics ap (physics at the college level) and got the result of my first test (59.2)! =( I am currently using the Cutnell and Johnson Physics Sixth Edition book...i was wondering is there a better book than this and if so what is it? Thanks...

ok i got back my test today and its some basic stuff, but i don't get the difference between AVG speed and AVG velocity. One of my problems was 'The length of the barrel of a blowgun is 1.2 meters. Upon leaving the barrel, a dart has a speed of 14 m/s. Assmuing that the dart was uniformly...

I can't seem to figure these problems if anyone can give me the concept and start me off that would be great. Thanks in advance Problem one: A car is traveling at a constant speed of 27 m/s on a highway. At the instant this car passes an entrance ramp, a second car enters the highway from...
