Water falling from a 50m high fall is to be used for generating electric power. If 1.8xx10^(5)kg of water falls per hour and half the gravitational potential energy can be converted into electric energy, how many 100 watt lamps can be lit ?

Water falling from a 50 m high fall is to be used for generating electric enegy. If 1.8xx10^5kg of water falls per hour and half the gravitational potential energyh can be converted into electric energy, how many 100 W lamps can be it?

Water falling from a 50 m high fall is to be used for generating electric enegy. If 1.8xx10^5kg of water falls per hour and half the gravitational potential energyh can be converted into electric energy, how many 100 W lamps can be it?

Water falling from a 50m high fall is to be used for generating electric energy. If 8xx10^5kg in water falls per hour and half the gravitational potential energy can be converted into electric energy, how many 100W lamps can be lit?

Water falling from a 50m high fall is to be used for generating electric energy. If 8xx10^5kg in water falls per hour and half the gravitational potential energy can be converted into electric energy, how many 100W lamps can be lit?

In generation of hydroelectric power, water falls from some height and gravitational potential energy of water is converted into electric power with the help of turbine. In one such event, 7.2xx10^4kg of water falls per hour from height 100m and half of the gravitational potential energy is converted into electric energy. How much power is generated?

A dam is used to block the passage of a river and to generate electricity. Approximately 5.73xx10^(4) kg of water fall each second through a height of 19.6 m. If one half of the gravitational potential energy of the water were converted to electrical energy, how much power would be generated ?
