I already turned it my assignment, i didnt get that one correct, but thank you though. :D

Homework Statement The figure below shows a finite line charge with linear charge density of λ and total length L. The point P shown is a distance s away from its end. Please calculate a formula for the electric field at point P, in terms of λ, L and s. Then use the following values...

Is my answer correct? i plug in 99.99% of the energy is stored in the spring but its wrong. I don't mean to be rude and i really appreciate your help if you can just tell me what i did is right or wrong and show me how to approach this problem instead of asking me back what am i thinking. If i...

Thank you, i got that one correct now. how about this one? how much is stored in the spring at maximum compression? ____% Since the kinetic energy of the block will be stored in the spring until the spring reach max compression so i set the equation as KEblock=PEspring 1/2(m1+m2)v^2=1/2kx^2...

Hi everyone, I am stuck with this problems. Homework Statement A block (m1 = 2.5 kg) sits at rest on a horizontal frictionless surface, connected to an unstretched spring (k = 190 N/m) whose other end is fixed to a wall. Another block (m2 = 1.0 kg) whose speed is 4.0 m/s collides head-on...

Chiro, thanks for all information. I really appreciate it. I will get the book and look at the material to get to know what thing that I will run into.

Chiro, do you know if there is any good basic programming lessons such as textbook, or some other things that i can use for self-study? I have nothing to do in my free time besides playing games. I think maybe i should start look at the book and teach myself rather than wasting my time on games...

I never take any programming class yet, and i don't know whether it is hard or no. But i had taken some basic electrical class, and i like it. I haven't really get into the program yet, I am still taking all the prerequisites courses for the program. Both Computer Engineer/Software Engineer and...

Hi everyone. I am stuck between Electrical Engineer and Software Engineer. I finished automotive program 3 years ago and currently work as auto mechanic. I like my job, but the pay isn't that high so i decided to go back and get a higher degree in engineering. Im currently taking all...
