Max has a group of goldfish in his tank at home. He notices that they are struggling a bit. Max wants to increase their rate of cellular respiration in hopes that it would help them to survive. Which of the following actions would potentially increase the rate of cellular respiration in the goldfish? a. Reducing the amount of food placed in the tank. b. Increasing the amount of carbon dioxide in the tank. c. Increasing the amount of oxygen in the tank d. Reducing the amount of sunlight that hits the tank.

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
