Two circular loops of wire are arranged so that they lie in the same plane and are concentric. one loop, of radius a, is much smaller than the other, which has radius b, i. e. a b. if the small loop is driven with a time varying current i1(t), derive an approximate formula for the induced emf in the large loop. be sure to state the approximations or assumptions that you make in your derivation.

tube or goog will be great resources to find the answer to the question that you're asking

what are the options.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
