Power = (14 x 10^6)(9.8)(52)
=71.34 x 10^8 joules/sec
= 71.34 x 10^8 watts
= 71.34 x 10^5 kw.

Water flows over a section of a waterfall at the rate of 2.5 ✕ 104 kg/s and falls 27 m. How much power is generated by the falling water? watts
Water flows over Victoria Falls, which is 128 m high, at an average rate of 1.39 × 106 kg/s. The acceleration of gravity is 9.81 m/s 2 . If half the potential energy of this water were converted into electric energy, how much power would be produced by these falls? Answer in units of MW.
In a small dam, water flows at a rate of 2500 kg/s and falls 30 m. After calculating the power wasted by the waterfall, how many 75 W light bulbs can be lit by this power? A)7350 bulbs B)75000 bulbs C)9800 bulbs D)2940 bulbs
Suppose the water at the top of Niagara Falls has a horizontal speed of 3.52 m/s just before it cascades over the edge of the falls. At what vertical distance below the edge does the velocity vector of the water point downward at a 78.3 ° angle below the horizontal?
Annie Edson Taylor was the first person to survive a “ride” over Niagara Falls in a barrel. On a day when the water is flowing relatively gently, water in the Niagara River moves horizontally at 5 m/s before shooting over the Falls, which are 53 meters high. (ONLY SOLVE FOR PART C) If we ignore air resistance, how long does it take for the barrel to reach the bottom of the Falls? (t=3.29s) How far horizontally will the barrel travel...
James Joule (after whom the unit of energy is named) claimed that the water at the bottom of Niagara Falls should be warmer than the water at the top, 51 m above the bottom. He reasoned that the falling water would transform its gravitational potential energy at the top into thermal energy at the bottom, where turbulence brings the water almost to a halt.. If this transformation is the only process occurring, how much warmer will the water at the...
Question 3 10 pts In a small dam, water flows at a rate of 2500 kg/s and falls 30 m. After calculating the power wasted by the waterfall, how many 75 W lightbulbs can be lit by this power? O 75000 bulbs 9800 bulbs 2940 bulbs 7350 bulbs
Approximately 1.0 x 106 kg of water falls 45 m over a waterfall each second. (a) What is the decrease in the gravitational potential energy of the water-Earth system each second? (b) If all this energy could be converted to electrical energy (it cannot be), at what rate would electrical energy be supplied? (The mass of 1 m3 of water is 1000 kg.) (c) If the electrical energy were sold at 3.3 cent/kW·h, what would be the yearly income in...
Water going over a fall splashes on rocks 20 m below. If 20 kg of water flows over the fall per second, how much force do the rocks exert on the falling water?
The great, gray-green, greasy Zambezi River flows over Victoria Falls in south central Africa. The falls are approximately 107 m high. If the river is flowing horizontally at 3.70 m/s just before going over the falls, what is the speed of the water when it hits the bottom? Assume the water is in free fall as it drops. HW 4.4 Problem Solving 4.84 7 of 7 Constants PartA The great, gray green, greasy Zambezi River flows over Victoria Falls in...
