You are trying to find a way to bring electricity to a remote village in order to run a water-purifying
device. A donor is willing to provide battery chargers
that connect to bicycles. Assuming the water-purifi-
cation device requires 18.6 kWoh daily, how many
bicycles would a village need if a person can average
100 W while riding a bicycle? Is this a useful way to
help the village? Evaluate your findings for strengths
and weaknesses. Summarize your comments and
suggestions in a letter to the donor.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
