If we have evidence that certain gases are harmful to our atmosphere, then why are we still using them?

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

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.)

What is the rate of change in a objects position?
