100 points. I need the answers PLEASE! (this is part of my test, and I have no idea what I am doing.) Will mark brainiest if you answer, this is one of my few questions. Bryan and Marc are two of my Ironman buddies and they have just had their fill at a local Subway and decide to do some Physics. Bryan has a mass of 85.0 kg with a pair of roller blades on. Marc pulls Ryan 5.00 m with a constant force and it takes him 7.66 s to accelerate Bryan from rest.

Calculate Average speed:

What was his initial speed (rest)? Vi

Calculate his final speed Vf. V=Vf+Vi

Calculate his acceleration.

Calculate the effective force Marc had on Bryan. F=ma

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
