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

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
