The arctic tern flies from the arctic to the antarctic and back every year, a total distance of 22,000 miles! in late summer, the terns start their migration south, and it takes about 3 months to go the 11,000 miles. what is the average velocity, in miles per day, that these birds travel? (remember, velocity also includes direction! )

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

spare some change and give it to the poor

explanation:

plz : ((

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
