How many joules of nutritional energy are in a bag of chips with a label that lists 245 Cal? If 1 lb of fat is stored by the body for each \(14.6\times10^3\mathrm{\ kJ}\) of excess nutritional energy consumed, how many bags of chips contain enough nutritional energy to result in 1 lb of body fat?

An Introduction to Thermal Physics 1
Problem 66P In analogy with the thermal conductivity, derive an approximate formula for the viscosity of an ideal gas in terms of its density, mean free path, and average thermal speed. Show explicitly that the viscosity Is Independent of pressure and proportional to the square root of the temperatur

a) Solve for the coefficients B1 and B2 of the form (II) of Problem 5.5 in terms of the initial position xo and velocity vo at t = 0. (b) If the oscillator's mass is m = 0.5 kg and the force constant is k = 50 N/m, what is the angular frequency co? If xo = 3.0 m and vo = 50 m/s, what are B1 and B2? S

The quartz crystal used in an electric watch vibrates with a frequency of 32,768 Hz. What is the period of the crystals motion?

Urban Economics 8
Rural versus Urban Development In the initial equilibrium, a nations workforce of 24 million is divided equally between a city and a rural area. The initial common utility level is $50. The urban utility curve has the conventional hump shape, with a peak at 8 million workers. In the workforce range 8

Urban Economics 8
Consider a modern city in which office employment has been steadily shifting from the city center to suburban locations along beltways. Suppose that the city improves its mass-transit system, decreasing the monetary and time costs of radial travel. Assume the improvement in the transit system does no
