Final answer:
The frequency of a heart beating at 146 beats per minute is 2.433 Hz, and the period of one heartbeat is approximately 0.411 seconds or 411 milliseconds.
Step-by-step explanation:
If during strenuous exercise your heart rate is 146 beats per minute, the following information can be determined:
(a) The frequency of your heartbeat in hertz (Hz)
Frequency is defined as the number of events that occur per unit of time. In the context of heart rate, it refers to the number of heartbeats per second. To calculate the frequency, we need to convert the heart rate from beats per minute to beats per second by dividing by 60 (since there are 60 seconds in a minute).
Frequency = Heart rate (in bpm) / 60 seconds/min = 146 beats/min / 60 s/min = 2.433 Hz
(b) The period of your heartbeat in seconds
The period of an event is the time it takes to complete one cycle of the event. In terms of heartbeat, it is the time for one heartbeat. The period is the reciprocal of the frequency.
Period = 1 / Frequency = 1 / 2.433 Hz ≈ 0.411 seconds or 411 milliseconds (ms)
