Calculate the magnetic field at the point P on the y axis. (i) This appears to be a horrendous problem, with no symmetry! But really, the hollow cylinder is a superposition of two solid cylinders ... and a solid cylinder of current is something we can deal with. How could you treat this system so that it consists of two solid cylinders

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational
