The technology in the picture produces which energy conversion

Kinetic energy to electrical energy

Explanation:

Chemical energy is the energy stored in the bonds of molecules.

Kinetic energy is the energy possessed by a body by virtue of its motion.

Electrical energy is the energy possessed by an object by virtue of flow of electrons.

Thermal energy is the energy possessed by a body by virtue of its temperature.

According to law of conservation of energy, energy remains conserved. It only transforms from one form to another.

In dams, the kinetic energy stored  in the running water which is made to fall from height converts to electrical energy by the use of turbines which are made to rotate and thus electricity is generated.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

the answer is   c.) 1575 j.
