1.	the lungs performs 2.4j of work during each expansion . how many times per minute do they expand if their power is 2 j/s ?
Answer» *P = 2 j/s* *work done during EXPANSION = 2.4 j ( W )* *t = 1 minute = 60 seconds* $P = \frac{W}{t}$ **W = P t* = 2 60 = 120 J* total no. of expansion per minute = 120 / 2.4 = 50 ( answer )**
