Answer: 80 beats
Explanation:
work = 1.5 J
time = 1 min = 60 sec
power = 2 Watt
to find: no. of heartbeats
W = Pt = 2 X 60 s = 120 J
work = 1.5 J
time = 1 min = 60 sec
power = 2 Watt
to find: no. of heartbeats
ans: W = Pt = 2 X 60 s = 120 J
V 1.5 J work is done in 1 beat.
.’. 120 J work will be done in 1.5 J= 80 beats
Therefore, number of beats per min = 80 1.5 J work is done in 1 beat.
.’. 120 J work will be done in 1.5 J= 80 beats
Therefore, number of beats per min = 80
