Consider interference between two waves from two sources of intensities i and 4i. What is the ratio of intensities at the point where the phase difference is π? * 1 point.

are their multiple choices ?

explanation:

iron would move it is magnetic there is a mag field around the current in the wire

mass and volume are the answers you are looking for

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
