Two long, straight, parallel wires, 10.0 cm apart carry equal 4.00-a currents in the same direction, as shown in the figure1. find the magnitude of the magnetic field at point p3, 20.0 cm directly above p1.the magnitude of the magnetic field at point p1, midway between the wires. is zerothe magnitude of the magnetic field at point p2, 25.0 cm to the right of p1. is 6.67�10? 6

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?

Ben (55kg) is standing on very slippery ice when junior (25kg) bumps into him. junior was moving at a speed of 8 m/s before the collision and ben and junior embrace after the collision. find the speed of ben and junior as they move across the ice after the collision. give the answer in m/s. describe the work you did to get the answer.
