In Hydroelectric power plant in the energy from moving water is converted into electric powered what kind of energy transformed occurs when the energy is converted

a) potential energy to kinetic energy  

b) kinetic energy to mechanical energy  

c) mechanical energy to electrical energy

Explanation:

In the hydroelectric power plant, following energy conversions take place -  

a)When water falls from great heights , its potential energy is converted to kinetic energy  

b)When fast moving water turns the blade of turbine, then its kinetic energy is converted into mechanical energy  

c)When the rotating turbine rotate the Electromagnetic coil of generator, the mechanical energy is converted into electrical energy.  

im guessing the west of station b

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
