Water flows over a section of Niagara Falls at the rate of 14.0 106 kg/s and falls 52 m. How much power is generated by the falling water?____MW
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.
A mass M = 10.0 kg falls through a height h = 1.00 m, whilst attached to a pulley which turns a paddle wheel in a tub of m = 0.0100 kg of water at T = 10.0 Celsius. If M starts from rest and hits the floor at 2.00 m/s, what is the temperature of the water after M hits the ground?
An elevator mass of 2600 kg falls from a height of 25 m after a sudden failure in the hoisting cable. The mass is stopped by a spring at the bottom of the shaft having a spring constant of 90 kN/m. Determine the spring's compression distance (in m) that brings the falling elevator momentarily to rest. An elevator mass of 2600 kg falls from a height of 25 m after a sudden failure in the hoisting cable. The mass is...
A dam collects water at a height of 300m. The water can be let down through a pipe. As it falls to the ground it loses potential energy but it gains kinetic energy. 100 tonnes (note 1 tonne 1000 kg) of water are let out from the dam and reach the ground, 300m below; all the gained kinetic energy is then harnessed by a perfectly efficient turbine and converted into energy to power houses in the valley. The Bureau of...
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
Water going over Iguacu Falls on the border of Argentina and Brazil drops through a height of about 72 {\rm m}. Suppose that all the gravitational potential energy of the water goes into raising its temperature Find the increase in water temperature at the bottom of the falls as compared with the top.
Rain is falling at the rate of 2.3 cm/h and accumulates in a pan. Water has a mass of 1.00 × 10^3 kg per m^3. If the raindrops hit at 8.3 m/s , estimate the magnitude of the force on the bottom of a 1.0-m^2 pan due to the impacting rain which we assume does not rebound.
