The diagram shows two vectors that point west and north. a right triangle with the base labeled 40 meters and the height labeled 30 meters. the hypotenuse is a dotted arrow labeled r. what is the magnitude of the resultant vector? 10 meters 50 meters 1200 meters 2500 meters

R=50 meters

Explanation:

We'll use the Pythagoras's theorem

A right triangle with legs of a=40 m and b=30 m has an hypotenuse of

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
