Step 1: interpreting the seismograms
⦁ estimate the times of the first arrival of the p waves and the s waves at each seismograph station. enter these times into your data table. reminder: you are trying to find the difference between the arrival time of the p wave and the s wave.
⦁ determine the difference between the arrival of the p wave and the arrival of the s wave, and enter this difference into the data table.

have a great day because if you dont you and i will be sad

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
