Two insulated wires, each 4.76 m long, are taped together to form a two-wire unit that is 4.76 m long. one wire carries a current of 7.84 a; the other carries a smaller current i in the opposite direction. the two-wire unit is placed at an angle of 69.9o relative to a magnetic field whose magnitude is 0.514 t. the magnitude of the net magnetic force experienced by the two-wire unit is 1.41 n. what is the current i?

What properties of a moving object are used in determining the object's energy of motion

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
