A 0.1 kg mouse is running along a countertop. The mouse has 1 J of gravitational potential energy. A 5 kg cat is sitting on top of a cabinet, stalking the mouse. The cat has 100 J of gravitational potential energy. A 10 kg dog is on the floor, barking at the cat. The dog has 0 J of gravitational potential energy. The acceleration due to gravity (g) is 10 m/s2. Order (or list) the animals (mouse, cat, and dog) according to their height, starting with the animal that has the most height and ending with the animal that has the least height. Be sure to use evidence from the first paragraph and reasoning to justify your answer/claim.

b.transmitters send radio waves, and receivers capture radio waves.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

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
