Steam at 120°c flows in an insulated 1% carbon steel pipe. the pipe inner radius is 10 cm and the outer radius is 11 cm. this is covered with a 3 cm thick layer of asbestos having a density of 577 kg/m3 . the outer asbestos surface is at 45°c. using carbon steel thermal conductivity, k=43 w/m-k and asbestos thermal conductivity k = 0.192 w/m-k, determine the heat transfer from the steam per meter of pipe length.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
