After pulling his car off to the side of the road during a rainstorm, travis isdismayed to find that the car has become stuck in the mud. travis ties oneend of a rope to the front of the car and the other end to a tree 12.00 m awayas shown. a. if travis can exert a force of 610 n on the rope, moving it 1.00 min the direction shown, how much force will the rope exert on the car? b. whyis this method better than simply tying a rope to the front of the car andpulling the car straight out?

0.19 m/s and 0.45 m/s

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
