What is the best definition for Joule (1 J = 1 kg x m2/s2): Group of answer choices Joule (J) is the amount of energy of a mass moving constantly. Joule (J) is the amount of energy of a 1 kg mass moving at a speed of 1 m/s. Joule (J) is the amount of energy of any mass moving at a speed of 1 m/s. Joule (J) is the amount of energy of a 2 kg mass moving at...

Q) What is the kinetic energy, in joules, of a molecule of oxygen moving at a speed of 255 m/s(use the appropriate prefix to avoid exponential notation) a) The equation for kinetic energy is ½mv2, and is in units of joules. What are the component units for joules in terms of mass and velocity? kg m^2/s^2 b) From the previous part, we know that the mass needs to be in units of kg. What is the mass of an oxygen...

6. The cardiac systems of mammals have some nice scaling properties. The external work of the heart, Ew is dependent on the blood pressure and the stroke volume and has dimensions of Joules. The metabolic turnover rate, EMTR has dimensions of joules/sec/kg. The mass of an animal is M (kg) and the heartrate is fn (usually in 1/min). Use the Buckingham Pi theorem to derive a realtionship between these 4 quantities. Recall that work (measured in joules, J ) has...

3) In this problem, you will use the relationship between the Joule (mechanical energy), the calorie (heat energy), and the Calorie (food energy). The relationship between the three is: 4,186 Joules = 1,000 heat calories = 1 food Calorie. 4,186] = 1,000 cal = 1 Cal. conversions, calculate how many times (and how many flights of steps) a 150 Ib person would have to climb the Sears Tower located in downtown Chicago if they ate a 500 Cal piece of...
