When people sleep, their metabolic rate is about 2.6*10^4 C/(s-kg). How many calories does a 25kg person metabolize while getting a good nights sleep of 8 hours?
Multiply the rate by 8hours (in seconds).
ooops. And multiply it by 25kg.
Ah, the mysterious ways our bodies function while we snooze! Let me crunch some numbers for you.
First, we need to convert the metabolic rate from joules to calories. In scientific terms, one calorie is approximately 4.186 joules. So, if the metabolic rate is 2.6 * 10^4 C/(s-kg), it would be equivalent to 2.6 * 10^4 * 4.186 J/(s-kg).
Now, let's calculate the total energy metabolized over 8 hours of sleep. Since we know that 1 hour is equal to 3,600 seconds, we can multiply the metabolic rate by the number of seconds in 8 hours and the weight of the person (25kg).
(2.6 * 10^4 * 4.186) * 3,600 * 25 = ??? (I'm a clown, not a calculator!)
Well, I'm afraid I can't do the math for you, but you can always grab a calculator and compute the result. Just remember, when it comes to sleep, we humans burn some calories, but not as much as running a marathon. Sweet dreams and happy calculating!
To find the number of calories a person metabolizes while sleeping, we need to multiply the metabolic rate (2.6*10^4 C/(s-kg)) by the person's weight (25 kg) and the duration of sleep (8 hours).
First, let's convert the duration of sleep from hours to seconds:
8 hours × 60 minutes/hour × 60 seconds/minute = 28,800 seconds.
Now, we can calculate the total calories metabolized:
Metabolic rate (C/(s-kg)) × weight (kg) × duration of sleep (s)
= (2.6*10^4 C/(s-kg)) × 25 kg × 28,800 s
Let's calculate this:
= 2.6*10^4 C/(s-kg) × 25 kg × 28,800 s
= 1.872 × 10^8 C
Therefore, a 25 kg person metabolizes approximately 1.872 × 10^8 calories while getting a good night's sleep of 8 hours.
To calculate the number of calories metabolized by a 25kg person during 8 hours of sleep, we will use the given metabolic rate of 2.6*10^4 C/(s-kg). Here's how you can do it:
Step 1: Convert the metabolic rate from C/(s-kg) to C/hour-kg.
Since there are 3600 seconds in an hour, we need to multiply the metabolic rate by 3600 to convert it to C/hour-kg.
2.6*10^4 C/(s-kg) * 3600 s/hour = 9.36*10^7 C/hour-kg
Step 2: Calculate the total number of calories metabolized per hour for a 25kg person.
Multiply the metabolic rate by the person's weight in kilograms.
9.36*10^7 C/hour-kg * 25 kg = 2.34*10^9 C/hour
Step 3: Determine the total number of calories metabolized during 8 hours of sleep.
Multiply the calories metabolized per hour by the number of hours of sleep.
2.34*10^9 C/hour * 8 hours = 1.87*10^10 C
Therefore, a 25kg person would metabolize approximately 1.87*10^10 calories during a good night's sleep of 8 hours.
