- Solve the question asap. Strictly don't use Artificial intelligence tools. (Chatgpt answer will be reported)After eating a 200 g bottle of yogurt, Bob decides to go for a run to burn off the extra energy. The yogurt provides 5.4 MJ kg-1, and Bob is able to raise his metabolic rate to 220 W while running. How long does he have to run?The recommended daily caloric intake is 2000 calories (8,400,000J). This is because this is the same value for how much the average body loses to heat and work in a typical day (your change in energy is zero because you take in the same amount of energy you lose). A) If you lose a total of 8,400,000J (Qout+W=total lost), but consume 1200 calories of food (5,000,000J), what would your change in energy be? B) Assuming your change in energy is negative (hint-it should be), where does your body get the extra energy to maintain it's temperature?
