The correct answer is:
$1.2 \mathrm{~Hz}, 0.83 \mathrm{~s}$
Frequency of human heart,
$$
f=\frac{72}{60} \mathrm{~Hz}=\frac{6}{5} \mathrm{~Hz}=1.2 \mathrm{~Hz}
$$
Time period, $T=\frac{1}{f}=\frac{1}{1.2}=0.83 \mathrm{~s}$
$$
f=\frac{72}{60} \mathrm{~Hz}=\frac{6}{5} \mathrm{~Hz}=1.2 \mathrm{~Hz}
$$
Time period, $T=\frac{1}{f}=\frac{1}{1.2}=0.83 \mathrm{~s}$
