Answer:
Gravitational potential energy
Explanation:
Hydroelectric dams are the power plants which generates electricity by using the energy of falling water from a great height.
A the water is stored in big reservoirs and at a great height, it contain lot of potential energy due to the height. As it falls downwards, the potential energy is converted into kinetic energy of the water. this kinetic energy of the falling water is used to run the turbine, and then the electric energy is generated.
So, in hydroelectric power stations, the potential energy of water is converted into the electric energy.
Answer:
2315.8 m/s
Explanation:
For the charged particle to pass through this field undeflected, the electric force and the magnetic force acting on it must be equal
Electric force = Magnetic force
Electric force = Eq
Magnetic force = qvB
qvB = Eq
v = (E/B)
E = 440 N/C, B = 0.19 T
v = (440/0.19)
v = 2315.8 m/s
The formula for potential energy is mass x height x gravitational force. Your mass is 5.3 kg and your height is 6.6 meters. The gravitational force on earth is 9.8 m/s. That means your answer is 5.3 x 6.6 x 9.8 and that equals 342.804
