Acircular loop 40 cm in diameter is made froma flexible conductor and lies at right angles to a uniform 12-t magnetic field. at time t = 0 the loop starts to expand, its radius increasing at the rate of 5.0 mm/s find the induced emf in the loop: a) at t 1.0 s and b) at t 10 s.

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels.the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause,directly and indirectly, for such a rise in sea level is
