An LR circuit contains an ideal 60-V battery, a 42-H inductor having no resistance, a 24- resistor, and a switch S, all in series. Initially, the switch is open and has been open for a very long time. At time t = 0 s, the switch is suddenly closed.
 
  How long after closing the switch will the potential difference across the inductor be 24 V?
  A) 1.8 s B) 2.1 s C) 1.4 s D) 1.6 s E) 1.9 s

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
