YES! the line integral, which I have no idea what that is so I'm looking it up. So using Ampere's law (which relates much better to this problem) I set up: The window is 1.5m wide (X) and 1m tall (Y) and I is 7 Amps B= 7*mu / 2X+2Y which equals 7mu / 5 So B = approximately 1.759e-6 Now...

Homework Statement Sounds like the beginning to a bad joke right? Two long straight wires pass through a window frame (1m x 1.5m). One wire carries 1A out of the room and one wire carries 8A in. Find magnitude of closed integral of vector B * vector dl around window frame. Answer in...

Ahh, the acceleration IS the derivative. So the integral with -.16 is the equation I need to use? What is the X in that equation then? time or distance?

Homework Statement The acceleration of an object in a fluid is proportional to its speed squared. If the object's initial speed is 1.13 m/s, how much time until its speed is reduced by half (0.565 m/s)? Homework Equations a=-.48v^2 The Attempt at a Solution I tried using the formula...
