Calculation of Work Done
To calculate the energy required by a human heart to beat in a day, we need to first calculate the work done by the heart in one beat. Given that the work done per beat is 0.5 J and the time period for one beat is T = 0.8 seconds, we can use the formula:
Work (W) = Force (F) × Distance (d)
Since the force exerted by the heart remains constant, we can rewrite the formula as:
Work (W) = Force (F) × Distance (d)
Distance (d) = Velocity (v) × Time (t)
We can substitute the value of distance (d) from the distance formula:
Work (W) = Force (F) × Velocity (v) × Time (t)
Given that the time period (T) is 0.8 seconds, we can calculate the velocity (v) as:
Velocity (v) = Distance (d) / Time (t)
Since the distance covered by the heart in one beat is not provided, we assume that the distance covered is constant for all beats. Therefore, the velocity can be calculated as:
Velocity (v) = Distance (d) / Time (t) = Constant
Calculation of Energy Required
The energy required by the heart to beat in a day can be calculated by multiplying the work done per beat by the total number of beats in a day.
To find the total number of beats in a day, we need to know the heart rate (number of beats per minute). Let's assume the average heart rate is 70 beats per minute.
Heart Rate (HR) = 70 beats/minute
Since there are 60 minutes in an hour and 24 hours in a day, the total number of beats in a day can be calculated as:
Total Beats in a Day = Heart Rate (HR) × 60 minutes/hour × 24 hours/day
Finally, we can calculate the energy required by the heart in a day by multiplying the work done per beat by the total number of beats in a day:
Energy Required = Work Done per Beat × Total Beats in a Day
Given that the work done per beat is 0.5 J, we can substitute the values to calculate the energy required:
Energy Required = 0.5 J/beat × Total Beats in a Day
Energy Required (in kcal) = Energy Required (in J) / 4184 J/kcal
The final answer will be the energy required by a human heart to beat in a day, expressed in kcal.
To calculate the energy required by a human heart to beat in a day, we need to first calculate the work done by the heart in one beat. Given that the work done per beat is 0.5 J and the time period for one beat is T = 0.8 seconds, we can use the formula:
