If two tiny identical spheres attract each other with a force of 3 N when they are 25 cm apart, what is the mass of each sphere?

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.)

True or false graphs must include scales that increase by the same amount

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is
