Seismic waves are the waves that transport energy away from the focus of an earthquake. seismometers, such as the one shown here, measure the shaking of the earth as a result of earthquakes. what information from seismometers do scientists use to determine the energy of an earthquake?

a. the period of the earthquake motion

b. the amplitude of the earthquake motion

c. the frequency of the earthquake motion

d. the speed at which the earthquake travels

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
