A typical candy bar weighs about 2.00 oz (1.00 oz = 28.4 g). (a) Assuming that a candy bar is 100% sugar and that 1.00 g of sugar is equivalent to about 4.00 Calories of energy, calculate the energy (in kJ) contained in a typical candy bar. × 10 kJ Enter your answer in scientific notation. (b) Assuming that your mass is 53.0 kg and you convert chemical potential energy to work with 100% efficiency, how high would you have to climb to work off the energy in a candy bar? (Potential energy = mass × g × height, where g = 9.81 m/s2.) × 10 m Enter your answer in scientific notation.

A 140 g bullet is fired from a rifle having a barrel 0.600 m long. Assuming the origin is placed where the bullet begins to move, the force (in newtons) exerted by the expanding gas on the bullet is 10000 + 6000x - 26000x^2, where x is in meters. (a) Determine the work done by the gas on the bullet as the bullet travels the length of the barrel (suggestion: enter your answer in kJ = kilojoules). (b) If the...

this is a thermodynamics class 4. We want to develop an intuition for what different amounts of energy look like in various forms. Calculate the energy in MegaJoules (MJ) present in the following systems. As a comment, many people will be surprised by some of the values, for example, a comparison of part e to parts a through c. a) 1 liter (approximately 1 quart) of octane, a primary component of gasoline. In this case, the chemical energy is released...

1. A woman expends 92 kJ of energy in walking a kilometer. The energy is supplied by the metabolic breakdown of food intake and has a 35 percent efficiency. a) If the woman drives a car over the same distance, how much energy is used if the car gets 8.0 km per liter of gasoline (approximately 20 mi/gal)? The density of gasoline is 0.71 g/mL, and its enthalpy of combustion is 49 kJ/g. b) Compare the efficiencies of the two...
