The actual density of seawater is 1029 kg/m3. by what percentage would the results of our calculations for the energy harnessed by tidal turbines change if we replace the density value we used in class of 1000 kg/m3, which best reflects freshwater, with the density of seawater?

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
