Enter your answer in the provided box. A single serving bag of snack chips contains 63.0 Cal. Assuming that all of the energy from eating these chips goes toward keeping your heart beating, how many hours can these chips sustain a heartbeat of 77 beats per minute? Note: 1 Cal = 1 kcal = 4.184 kJ and each heartbeat requires approximately 1 J of energy. hr

A Mountain bar has a mass of 6.9×10−2 kg and a calorie rating of 320 Cal . What speed would this candy bar have if its kinetic energy were equal to its metabolic energy? [Note: The nutritional calorie, 1 Cal, is equivalent to 1000 calories (1000 cal) as defined in physics. In addition, the conversion factor between calories and joules is as follows: 1 Cal = 1000 cal = 1 kcal = 4186 J.] Express your answer using two significant...

Think about operationalizing concepts in your life; how would you define and measure the things you feel or talk about? When an undefined concept comes up in a conversation, take the opportunity to operationalize it. Define how you would measure this concept, hopefully during this same conversation (but you can fictionalize it after, if need be). Type up the conversation; after the dialogue, note the concept that you made an operational definition for, and explain what the definition is (including...
