You have a piece of copper wire and a piece of carbon rod, each 1.5 m long and each having a cross-sectional area of 8.0 × 10−6 m2. When you connect the copper wire to the terminals of a 9.0-V battery, the current in the wire is I. Part A If you want to connect the carbon rod to another battery and have the same current I in the wire, what must the potential difference of the battery be? [ σcopper = 5.9 × 107 A/(V⋅m), σcarbon = 7.3 × 104 A/(V⋅m) ]

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt

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
