the heart does 1.2 joule of work in each Heartbeat how many times per minute does it beat if its power is 2 Watt
Answers
The heart beats 100 times per minute.
Explanation:
=> It is given that,
Power of the heart = 2 watt = 2 joule per second = 2 * 60 = 120 joule per minute
time taken, t = 1 min = 60 sec
The work done during each Heartbeat = 1.2 joule
=> Heartbeat per min:
number of times heart beat per min = total workdone/ work done in each minute
= 120 / 1.2
= 100 times
Thus, the heart beats 100 times per minute.
