Hydroelectric energy is inexhaustible. select the best answer from the choices provided: t f

True

Explanation:

The hydroelectric energy is generated by the utilization of potential energy of water currents which are utilized to run the water turbine. The mechanical energy generated after this process is used to generate electricity.

The hydroelectric energy is a renewable source of energy as the water in the ocean or large river reservoir will not dried up and will be avialable for generation of electrical energy for many years.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
