A demonstration helps students understand a principle of roller coaster design. Which answer choice correctly describes the ball's kinetic and potential energy? A) The ball has more potential energy at position X than at position Z. B) The ball has more kinetic energy at position Y than at position W. C) The potential energy and kinetic energy of the ball are equal at position X. D) The potential energy and kinetic energy of the ball are greatest at position Z.

The ball would have the most kinetic energy at the lowest point and the most potential energy at the top of the hill

Explanation:

Since you didnt add the picture I cant tell which multiple choice answer it would be, but I hope this helps :)

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
