    Waterfall is 210 m high. Temperature of water at top is 10.0 degrees cels. And 10.5 degrees cels at bottom. Calculate the specific heat capacity of water. State any assumption you have made regarding energy in your calculation

    What did you do?

    How do you think you can solve this?

    Your hint in the question is the 'State any assumption'. This assumption is that you are assuming all energy is conserved and thus, the potential energy of the water at the top has partly been converted to heat energy, and the rest to kinetic energy.

    Post what you did.
