A pair of wires, one which covers the x axis, the other covering the line y = 2x has a bulb with resistance R = 5Ω is attached to the wires at the origin. A long metal bar is placed vertically so that it touches both wires at x = 5 cm. A uniform magnetic field B~ = 1Gsˆz fills all space. If at t = 0 we begin to move the bar smoothly from x = 5 cm to x = 10 cm how much energy is consumed by the bulb if it takes: a) 5 s b) 1 s

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

answerscientific theory;
