earthquake generates sound 1
waves in earth. unlike in a
gas, there are both z
longitudinal (p) and
transverse (s) sound waves in
solid. typically, the speed of s
waves is about 4.5 km/s and
that of p-waves 8.2 km/s. a
seismograph records p& s waves from an earthquake. the first p
waves arrive 3 minute before the first s waves. how far away did
the earthquake occur?
ans: 1795 km

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

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.
