A child in danger of drowning in a river is being carried downstream by a current that flows uniformly with a speed of 2.0m/s. The child is 200mfrom the shore and 1500mupstream of the boat dock from which the rescue team sets out. If their boat speed is 8.0m/swith respect to the water, at what angle from the shore should the pilot leave the shore to go directly to the child

answer: decibel

explanation:

heats surface water up

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
