You measure the resistivity of the wire in the following way: you connect one end of the wire to one terminal of a battery that has emf 12.0 v and negligible internal resistance. to the other terminal of the battery you connect a point along the wire so that the length of wire between the battery terminals is d. you measure the current in the wire as a function of d. the currents are small, so the temperature change of the wire is very small. part a m . what is the resistivity of the material of which the wire is you plot your results as i versus 1/d and find that the data lie close to a straight line that has slope 600 a made? express your answer in ohm-meters. 0 aed + o ? 12.m

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

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
