Part 1: what is the total calories that the man would gain if he only ate 225 grams from his steak?
Part 2: How many oz from the steak would the wife eat.
21.0 calories is equal to how many joules?
Electrical energy is usually measured in kiloWatt-hours, kWh. A Watt
is 1 joule per second. A kiloWatt is 1000 joules per second. An hour
has 3600 seconds. Therefore 1 kWh = 3.6x106 joules.
How many kWh are there in a meal that is 776 Cal, or nutritional
calories? Just put in the number. The assumption is the unit is kWh.
1 Nutritional Cal = 1 kcal (exact)
1 cal = 4.184 joules (exact)
kilo 103 (exact)
1 kWh = 3.6x106 joules (exact)
=

- As a child plays on a swing, at what point in her movement is her kinetic energy the greatest? At what point is potential energy at its maximum?arrow_forwardExplain the economic importance of conversions between different forms of energy and the inevitability of losses in this process.arrow_forwardDuring a recent winter month in Sheboygan, Wisconsin, it was necessary to obtain 3500 kWh of heat provided by a natural gas furnace with 89% efficiency to keep a small house warm (the efficiency of a gas furnace is the percent of the heat produced by combustion that is transferred into the house). (a) Assume that natural gas is pure methane and determine the volume of natural gas in cubic feet that was required to heat the house. The average temperature of the natural gas was 56 F; at this temperature and a pressure of 1 atm, natural gas has a density of 0.68 1 g/L. (b) How many gallons of LPG (liquefied petroleum gas) would be required to replace the natural gas used? Assume the LPG is liquid propane [ C3H8 : density, 0.5318 g/mL; enthalpy of combustion, 2219 Id/mo for the formation of CO2(g) and H2O(l) ] and the furnace used to burn the LPG has the same efficiency as the gas furnace. (c) What mass of carbon dioxide is produced by combustion of the methane used to heat the house? (d) What mass of water is produced by combustion of the methane used to heat the house? (e) What volume of air is required to provide the oxygen for the combustion of the methane used to heat the house? Air contains 23% oxygen by mass. The average density of air during the month was 1.22 g/L. (f) How many kilowatt—hours ( 1kWh=3.6106 J) of electricity would be required to provide the heat necessary to heat the house? Note electricity is 100% efficient in producing heat inside a house. (g) Although electricity is 100% efficient in producing heat inside a house, production and distribution of electricity is not 100% efficient. The efficiency of production and distribution of electricity produced in a coal-fired power plant is about 40%. A certain type of coal provides 2.26 kWh per pound upon combustion. What mass of this coal in kilograms will be required to produce the electrical energy necessary to heat the house if the efficiency of generation and distribution is 40%?arrow_forward
