Finally, the switch on the electromagnet is reopened. the magnitude of the external magnetic flux through the wire loop (a. increases, b. decreases, c. remains constant), and there is (a. zero, b. a clockwise, c. a counterclockwise) current induced in the loop (as seen from the left). enter the letters corresponding to the responses that correctly complete the statement above. for example, if the correct answers are a and c, type

Decreases ,,clockwise

Explanation:

         When  the switch is reopened then magnitude  of magnetic  flux through the   loop will decreases and  the direction of induced  current will  be clockwise  (when seen from clockwise.

So the  answer of the  fill in the  blank is decreases and  clockwise.

Answer - B  and B.

              B)  Decreases ,B)clockwise

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
