Answer the following question given this paragraph: Seismograms contain a lot of information about an earthquake: its strength, length, and distance. Wave height is used to determine the magnitude of the earthquake. The seismogram shows the different arrival times of the seismic waves ( Figure below ). The first waves are P-waves since they are the fastest. S-waves come in next and are usually larger than P-waves. The surface waves arrive just after the S-waves. If the earthquake has a shallow focus, the surface waves are the largest ones recorded. Q: What measurement of the wave is used to determine the magnitude of an earthquake? Choices: - length - diameter - width - height A:
(Answer)
height

Answer the following question given this paragraph: DeBroglie proposed in 1924 that any object exhibits a wavelength that is inversely proportional to its momentum. Because of this relationship, only very tiny particles will exhibit measurable wavelengths. Q: Debroglie proposed in 1924 that any object exhibits a wavelength that is inversely proportional to its? Choices: - inertia - frequency - velocity - momentum A:
(Answer)
momentum
