The wavelength range of colors visible to humans ranges from 350 nm to 750 nm. light that most of us perceive as is at 750 nm.

What is the angular momentum of the bar about the axle?

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.

When solid surfaces slide over each other the kind of friction that occurs is called friction
