Question

the power of a typical human heart is about 1 W . How much energy is used by a typical heart in one hour​

Answer 1

Step-by-step explanation:

Power is 1 W . That means it is using energy of one joule in one second.

one hour = 60 x 60 seconds

work one by heart in one hour = 3600 x 1 = 3600 J

energy used by it in one hour = 3600 J .
