Two straight rods 55 cm long and 1.4 mm apart in a current balance carry current I, each in opposite directions. If a mass of 1.3 g when placed on the upper rod balances the magnetic force of repulsion between the rods, then calculate the current I.

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

do you have a formula possibly

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
