Two sites on the same river have been surveyed as a place to build a dam. The dam will be part of a hydroelectric power plant. Site A is at the top of a 50-meter waterfall. Site B is at the top of a 35-meter waterfall. Which answer correctly describes where the water will have the greater gravitational potential energy to be converted into electricity? A. Site A
B. Neither site has gravitational potential energy to convert to electricity.
C. Both sites will produce the same amount of electricity as the water flows over the water fall.
D. At both sites the water has the same gravitational potential energy.

Site A because it has a higher percentage

Ultra-high temperature (uht)

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
