Acar on a straight flat road races a boat on a calm canal parallel to the road. the car has a constant acceleration of 1.95m/s2 and reaches a top speed of 41.0m/s. the boat has a constant acceleration of 6.50m/s2 and reaches a top speed of 32.0m/s. the car and the boat accelerate to their top speed and then maintain their top speed for the rest of the rest. they race for 1.2km. which vehicle wins the race?

none, its a machine

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
