Asinusoidal electromagnetic wave is propagating in a vacuum in the +z-direction.
if at a particular instant and at a certain point in space the electric field is in the +x-direction and has a magnitude of 3.40v/m, what is the magnitude of the magnetic field of the wave at this same point in space and instant in time?

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
