Draw the field lines for two infinitely long wires one running along the y axis and one running along the x axis, both charged uniformly with lambda C/m. Make an expression for the electric field E at any point in the xy plane in terms of x and y. Any help is much appreciated. Thanks in advance.
A flat sheet of crystalline quartz has a thickness of 3.7cm. It is on top of a flat sheet of diamond that has a thickness of 2.6cm. Light strikes the crystalline quartz vertically and travels through it and then through the diamond.
A 1348 kg weather rocket is launched straight up. The rocket motor provides a constant acceleration for 13.6 s, then the motor stops. The rocket altitude 29.6 s after launch is 2091 m. You can avoid any effects of air resistance. What was the rock..
