A wave is described by the function y(x, t) = (3.00 cm)cos[(3.00 m-1)x + (4.00 s-1)t]. What is the wavelength of this wave?

In a region of space, a magnetic field points in the +x-direction (toward the right). its magnitude varies with position according to the formula bx=b0+bx, where b0 and b are positive constants, for x≥0. a flat coil of area a moves with uniform speed v from right to left with the plane of its area always perpendicular to this field. part a what is the emf induced in this coil while it is to the right of the origin?
