Below are steps of a work out from warm up steps through the cool down. Place steps in order from 1 being the first thing to do when starting a session to 5 being the last part. Question 1 options: 2 Static stretches held for 10 seconds each stretch to loosen up. 1 Light jog to get heart rate up for about 5 minutes. 4 Activity specific drills such as high knees, butt kicks, skipping, grapevines. 5 15-45 minute exercise or sport activity. 3 Walk to bring heart rate down, followed by stretches held for as long as 30 seconds.

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
