Can anyone help me?

Homework Statement Assume that the current flowing into the loop is 0.500A . If the magnitude of the magnetic field is 0.300 T, what is torque , the net torque about the vertical axis of the current loop due to the interaction of the current with the magnetic field? the loop is initially...

can any help me, i still don't get it

Homework Statement A point charge with charge q1 is held stationary at the origin. A second point charge with charge q2 moves from the point (x1, 0) to the point (x2,y2). How much work W is done by the electrostatic force on the moving point charge? Express answer in joules. Use k for...

I figured out the Uinital=-2.42e-17J, Kinitial= 0J, Ufinal is -5.15e-17J where do i go from here

Homework Statement . Homework Statement Two stationary positive point charges, charge 1 of magnitude 3.25 nC and charge 2 of magnitude 1.55nC , are separated by a distance of 57.0cm . An electron is released from rest at the point midway between the two charges, and it moves along the...

can anyone help me

do you know of any equations that could help me

Homework Statement Two stationary positive point charges, charge 1 of magnitude 3.25 nC and charge 2 of magnitude 1.55nC , are separated by a distance of 57.0cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two...

thanks for the help

Do i set e= 0.15 to the equation above? and if i do how do i go about getting the answer?

Thats all mastering physics gives me. A problem like that is in the book but the efficiency of the engine is 11% instead. They get 450 K for Tc

[SOLVED] Heat Engines and the Carnot Cycle Homework Statement The operating temperatures for a Carnot engine are Tc and Th= Tc + 55K. The efficiency of the engine is 15%. How do i find Tc?

thanks for all your help

For T i get 859.5 How do i get the inital temperature
