Understanding Electric Fields and Calculating E= dV/dS
That the thing I have no idea. All we did was connect a battery and draw on a Electric field mapper. have no idea what the lines mean.- cheater1

Understanding Electric Fields and Calculating E= dV/dS
Homework Statement OK we had a lab and the lab was to draw some dots mapping a electric field. I connected the dots, but i have no idea which way the field points and how to calculate the electric field. I think we need to use E= dV/dS , but i have no idea what dS is. Do i just take the...- cheater1

Why Don't We Need to Consider Net Force in Rotational Static Equilibrium?
ok I am no expert but i got the sign to be 30.4 kg. My class is in the same subject right now. so if you know the answer and it is somewhat similar to mines I can tell you how I did it. I don't want to tell you the wrong thing until the answer is confirmed.- cheater1

Solve Equilibrium Problem: Two Uniform Beams, Hinge & Chain
FxsinθL - WcosθL / sin θL = Tension edit: FxsinθL - WsinθL / sin θL = Tension then it will simplfy as , T = Fx-W = Tension... now it doesn't even seem right- cheater1

Solve Equilibrium Problem: Two Uniform Beams, Hinge & Chain
Homework Statement http://img820.imageshack.us/img820/3505/23625990.jpg Two uniform beams, each of mass M and length L, are connected by a hinge at the top and by a chain of negligible mass attached between their centers. The system will stand upright on a frictionless surface as shown in...- cheater1

Represent (1+x)/(1-x) as a power series.
ohh i see it now, thanks you. My class just started this section and I'm kinda new to this. Is there a shortcut of doing this or I have to write out the terms to find power series?- cheater1

How to Calculate the Alpha Particle's Velocity After Collision?
A proton with initial kinetic energy (5.2 MeV) collides with an alpha particle (initially at rest). The collision is perfectly elastic and the proton travels off at an angle of 133o relative to its initial direction. What is the velocity of the alpha particle after the collision? Assume the...- cheater1
