Answer to Question 1

Number of cells = 12 V/0.5 V/cell = 24 cells connected in series.

Answer to Question 2

A tidal barrage power system consists of a dam that stretches across an estuary, harbor or river that connects to the ocean. When the tides rises, sluice gates open to allow the tidal flow to move through tunnels to fill the area behind the dam. The flowing water produces electricity by spinning a turbine and generator. When the tide reaches its highest level, the gates close capturing the water behind the dam. As the tide drops, water can again flow through the tunnels and produce electricity.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
