Figure OQ31.2 is a graph of the magnetic flux through a certain coil of wire as a function of time during an interval while the radius of the coil is increased, the coil is rotated through 1.5 revolutions, and the external source of the magnetic field is turned off, in that order. Rank the emf induced in the coil at the instants marked A through E from the largest positive value to the largest-magnitude negative value. In your ranking, note any cases of equality and also any instants when the emf is zero.
 
  1.C = D > B = A > E
  2.E > A = B = 0 > C > D
  3.A > B > D > C > E
  4.E > A > B = D = 0 > C

Answer to Question 2

In simple terms, Bernoulli's principle states that where the velocity of a fluid is
maximum, the pressure is minimum. Where the pressure is minimum, the velocity of
the fluid is maximum.

A serious new warning has been established for pregnant women against taking ACE inhibitors during pregnancy. In the study, the risk of major birth defects in children whose mothers took ACE inhibitors during the first trimester was nearly three times higher than in children whose mothers didn't take ACE inhibitors. Physicians can prescribe alternative medications for pregnant women who have symptoms of high blood pressure.
