Acar drives toward the right over the top of a hill, as shown below. an illustration of car at the top of a hill pointing right and looking at the side of the car. the is a vector up labeled z, a vector down labeled x, a vector left labeled y and a vector right labeled w. which arrow represents the centripetal acceleration? w x y z

X

Explanation:

This situation can be illustrated as a car in circular motion (image attached).

In circular motion the acceleration vector is always directed toward the center of the circumference (that's why it's called centripetal acceleration).

So, in this case the arrow labeled X is the only that points toward the center, hence it represents the car's centripetal acceleration

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
