Hydroelectric power is produced by
a. falling water that turns a turbine.
b. tides that pour through a dam barrier.
c. hot water that comes from deep underground.
d. electric current that flows across a dam.

Hydro electric power is the process of  production of electricity from the mechanical energy of water.

In the process of generation of  hydro electricity ,large dams are constructed  in which the water is stored.The water present at top of the dam has potential energy.The water is driven downward  with high pressure. During the falling of water,the potential energy of the water is converted into equivalent kinetic energy. The water coming down with a heavy speed is allowed to fall on a turbine which is connected to a generator.

The mechanical energy of water drives the turbine and electricity is generated due to the electromagnetic induction .

Hence the option A is right i.e falling water that turns the turbine.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
