In a game of football, a 94 kg player carries the ball and heads toward the opponent’s end zone with a
velocity of 6.0 m/s [W]. A linebacker delivers a vicious hit, causing the ball carrier to be knocked
backward with a velocity of 2.7 m/s [E]. Determine the impulse delivered to the ball carrier and the
force of the hit if it took the linebacker just 0.38 s to deliver the hit.

idk sorry i only needs point for apex

explanation:

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
