- O 12. Which formula represents the law of conservation of energy? OPE,= mgh 9 ME=KE + PE MEnitial = MEfinal 1 KE= mv² OThe 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?Font words English (U.S.) e to search 6.

- Some of the following sources listed are currently used, while others might be more feasible in the future with more research. Fossil fuels Nuclear energy Biofuels Wind energy Solar energy You will research how the energy is extracted or produced and try to be very detailed about the process and the chemistry involved (stating equations and reactions). You will also research the impact on the environment when using or producing fuels. Investigating fossil fuel: How is it produced? What is the chemistry involved (stating equations and reactions)?
