A circular coil has 275 turns and a radius of 0.045 m. The coil is used as an AC generator by rotating it in a 0.500 T magnetic field. At what angular speed should the coil be rotated so that the maximum emf is 175 V?
Help, please! =)
Two sinusoidal waves in a string are defined by the functions
y1 = (2.00 cm) sin (20.0x - 32.0t)
and
y2 = (2.00 cm) sin (25.0x - 40.0t)
What is the positive x value closest to the origin for which the two phases differ by +/- pi at t = 2.00s? (This location is where the two...
