Carly is investigating the effects of heat transfer on molecular motion. She pours cold water into a beaker, places the beaker on top of a heat source, and turns on the heat. Her set up is shown. Identify and describe the method of heat transfer that Carly is investigating. Describe the effect of the heat transfer on the motion of the water molecules at the top and the bottom of the beaker.

what is the question because that is not a question.

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
