Suppose that the weight of an newborn fawn is Uniformly distributed between 2.4 and 3.5 kg. Suppose that a newborn fawn is randomly selected. Round answers to 4 decimal places when possible . a. The mean of this distribution is b. The standard deviation is c. The probability that fawn will weigh exactly 2.9 kg is P(x = 2.9) = d. The probability that a newborn fawn will be weigh between 2.8 and 3.1 is P(2.8 < x < 3.1)...

Suppose 1.16 kg of water at 11.6 ◦C is mixed with 1.7 kg of water at 81◦C. After equilibrium is reached, the mixture has an uniform temperature of 52.8517◦C. What is the change in entropy of the system? The specific heat of water is 4186 J/kg · K. Answer in units of J/K.

Heat Transfer in a Steel Pan A medium sized steel pan is used to boil water...

Heat Transfer in a Steel Pan A medium sized steel pan is used to boil water on top of an electric range. Approximately 85% of the 1000 W produced by the heating unit is transferred nearly uniformly into the pot during use. Express the most appropriate form of the heat diffusion equation that describes the heat transfer through the bottom section of the pan. Include all relevant boundary conditions. The bottom section of the pan has a thickness of 0.5...
