A resistor in an electrical circuit is analogous to a non-conservative mechanical force. What is this force

Lets say that an object of a certain volume has a certin mass. what happens to its mass when you double its volume?

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.)

Which of the following is an example of units for speed
