Find the total amount of heat Q lost through a wall 10' by 18', with R value from q. 1. Inside temperature is 70°F while outside is 45°F.

Two resistors, with resistances R1 and R2, are connected in series. R1 is normally distributed with mean 65 and standard deviation 10, and R2 is normally distributed with mean 75 and standard deviation 5. a. What is the probability that R2 > R1?

When a gas in a piston cylinder device is compressed, and as a result temperature rises. This process is a work interaction. a) True b) False

Consider a 1000-W iron whose base plate is made of 0.5-cm-thick aluminum alloy 2024-T6 (rho = 2770 kg/m3 and cp = 875 J/kg·°C). The base plate has a surface area of 0.03 m2. Initially, the iron is in thermal equilibrium with the ambient air at 22°C.

Madison and Oxford are the same distance from the equator and they are both near the ocean. Use the information on the map to answer these questions: How does the air temperature of Madison compare to the air temperature of Oxford? Why?
