Question

the average work done human heart while it's beat is 0.5 j . Calculate the power used by heat if it beats 72 times in a min .

Answer 1

Heya......!!

Work done =>> 0.5 j
Total work done during 72 beats in 1 min » 72 × 0.5 = 36 J

Power = work done / time
➡➡ 36/60 =>> 0.6 W .


Hope it helps u

Answer 2

power = 1.2 W  

Explanation:

given data

Work done = 0.5 j per beat

beats = 72 time in a min

solution

we know that power is express as

power = $\frac{work\ done}{time }$     .................1

here time is 60 min

and work done is = 72 × 0.5 = 36  

put value in equation 1 we get

power = $\frac{36}{60}$  

power = 1.2 W
