Calculate the total heat content of 10 kg of ice at -23°c. (hint: a substance at absolute zero, -273 degrees c, has 0 heat content.)
acceleration is a change in velocity, either an increase in speed or a change in direction. acceleration measures the rate of change of an object's velocity. average acceleration is calculated by dividing the change in velocity over the time.
the total energy at any point along the arc of swing of a moving pendulum is always the same number. what changes is how it's divided up between potential and kinetic energy.
radio waves are used in thing like cells phone and radios. they are transmitted to our radio which then use them to make vibrations in our speaker and produce the sound waves we hear.
the pull of gravity on the rocket decreases
