An object is changing its speed from 5 m/s to 15 m/s. What is acceleration

Natural forces that can alter ecosystems include seasons and climate changes. t or f

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.)
