Help Plz ;) In the diagram below, 4 pairs of metal spheres of equal size sit on a level surface the same distance apart. However, the type of metal each sphere is made from changes the mass of these spheres. Which pair of metal spheres has the greatest gravitational attraction between them?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.
