A. Food Energy. Energy is stored in food as the potential energy of the electrical bonds in molecules. Your body converts food energy to mechanical energy and heat. Food energy is expressed in “calories”, which are actually kilocalories (kcal, with 1 kcal= 4.185 kJ) How many joules are in a 130-kcal serving of breakfast cereal? B. A glass of 1 percent milk contains 130 kcal. How many glasses would a 70-kg person have to drink to get the energy needed...

Professor Goetz took a heavy marine 100 foot, 0.75 lb per foot rope and through it through his office window. One end of the rope touches the ground. Professor Goetz missed his lunch and can only exert 300kcal (the equivalent of a healthy sandwich). He realized he does not know if he has enough energy to lift the rope back into his office. a) How much energy in kcalories is needed to lift the rope half way from the ground....

A local high school requires every student fill out a survey for incoming students. After all 1,250 students finish the survey, the information is compiled and used to get population parameters for the student body. Student Council is deciding whether or not to add a soda vending machine to the cafeteria. Luckily one of the questions on the incoming survey was “On average, how many soft drinks do you drink each day?” Looking at all of the responses, they find...

Energy provides an easy measure of the vital needs for us to survive over a wide variety of foods and nutrients. For historical reasons, a number of units have been developed and used to quantify energy, such as J, Cal, kCal, BTU. Suppose that a normal person consumes (and therefore emits) 2000 kCal of energy per day. We also know that in New England, it takes approximately 45 BTU of energy per day to keep one square foot of house...

Question 7 Item 7 (The following passage is excerpted from an article published in the Journal of the American Dietetic Association in 2003.) Obesity (including overweight) is the principal public health nutrition problem in the United States, largely because of its ability to increase chronic disease risk and its increasing prevalence among adults and children. The rapidity of the increase is startling. The prevalence has increased sharply just within the past decade, and the increase is occurring so quickly that...
