The child’s inhalation-exhalation cycle is 36 times per minute. Determine the cycle frequency.

Given:

N = 36 – the child’s inhalation-exit cycle;

t = 1 minute – time interval of one inhalation-exhalation cycle.

It is required to determine u (Hertz) – the frequency of the inhalation-exhalation cycle.

Let’s convert time units from minutes to seconds:

t = 1 minute = 1 * 60 = 60 seconds.

Then we find the cycle frequency by the following formula:

u = N / t = 36/60 = 6/10 = 0.6 seconds-1 = 0.6 Hertz.

Answer: the frequency of the child’s inhalation-exhalation cycle is 0.6 Hertz.
