Answer please, I really need some help

Which of the following is considered to be a vector?               a.  temperature    b.  velocity    c.  time    d.  mass

Identify the type of synthetic material used in each object

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.)
