The friends recently learned that when light from the sun hits our atmosphere from the vacuum of interplanetary space, it is refracted, much like a beam of light passing from air to water. tristan asks camilla how this affects the apparent rising and setting times of the sun. which response is correct?

(a) "the sun appears to rise sooner, and set later than it actually does."
(b) "the apparent rising and setting times of the sun are completely unaffected by refraction."
(c) "the sun appears to rise sooner, and set sooner than it actually does."
(d) "the sun appears to rise later, and set later than it actually does."

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

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.
