A 50-kilogram object in outer space is attracted to a nearby planet with a
force of 400 newtons. What is the object's acceleration? *

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.)

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

Work out sian speed for the first 30 minutes of her journey. give your answer in km/h.
