The heart rater (the number of heart beats per minute) scales as 1/L,

1.	The heart rater (the number of heart beats per minute) scales as 1/L, where L is the characteristic length of the mammal. (a) Can you explain this? (b) The scale factor of a human relative to a rhesus monkey is about 2.5. What is the monkey's heart beat rate?
Answer» (a) Human heart rate is about 70 beats/min. More the characteristic length of the mammal, smaller is the heart-beat rate. (b) As scale factor of a human relative to a rhesus monkey is about 2.5, therefore, monkey's heart beat rate is 70 x 2.5 = 175
