A CHILD CONSUMED .23 KG OF JUICE WITH 115 CALORIES PER 1.15 SERVING. HOW MUCH WORK MUST PERFORMED TO REMOVE THESE CALORIES?
PER 1.15 SERVING
What are the units for this 1.15?
You have capitalized Calories...is this a food Calorie, or an old cgs energy unit?
im sorry , there is no unit indicated in 1.15 and the calories is with the small c :)
To determine the amount of work required to remove calories from the body, we need to understand the concept of calories and their relationship to energy.
Calories are a unit of energy, specifically the amount of energy needed to raise the temperature of 1 kilogram (kg) of water by 1 degree Celsius. In this case, we have a child who consumed 115 calories from a 1.15 serving of juice.
To calculate the energy content of the juice consumed by the child, we can divide the total calories by the serving size:
Energy content of juice = (115 calories) / (1.15 servings) = 100 calories per serving.
The child consumed 0.23 kg of juice, so we can multiply the energy content per serving (in calories) by the serving size (in kg) to find the total energy consumed:
Total energy consumed = (0.23 kg) x (100 calories/serving) = 23 calories.
Now, to remove these calories, we need to perform work. In this context, work refers to the energy expenditure required to burn off the calories consumed. Different activities have different energy expenditures, but we can use the concept of "metabolic equivalents" (METs) to estimate the energy expenditure.
MET is a unit that measures the amount of energy expended during physical activity compared to the energy expended at rest. We'll assume a MET value of 3.5, which is an average value for light physical activity.
To calculate the work required to remove the calories, we can divide the energy content (in calories) by the energy expenditure (in METs):
Work required = (Total energy consumed) / (MET value) = 23 calories / 3.5 METs ≈ 6.57 METs.
Therefore, approximately 6.57 METs of work need to be performed to remove the 23 calories consumed from the juice. It's important to note that the actual work required will depend on factors such as the individual's weight, age, and level of physical fitness.
