Consider the white frost problem. Recall that on a still night, the heat lost by the dew on the grass by radiation is equal to the energy gained by convection. Let us consider a patch of dew on the top of the grass for which all the radiant energy leaving it goes to outer space. Further, if we assume the dew to be a black body and outer space to be a black body at -40°F, at what air tempera- ture will the dew temperature drop to 32°F if the convective heat transfer coefficient between the dew and the air is 5 Btu/hr-ft²°F?

A dust particle is suspended in the air (floating due to a small updraft and its own low mass) when a powerful loudspeaker plays a very low note (2 Hz so it can’t be heard but you can actually see the speaker move!). How will the dust particle move as a result of the speaker  being turned on? Question 3 options: A) The dust particle will move up and down. B) The dust particle will be pushed across the room. C) The dust particle will move in a circular path. D) The dust particle will move side to side.
4. Jack, an engineering student, is taking in the great view while he was on the ship's deck, but as he is enjoying the cold wind tickling his face, he noticed that there is an iceberg about to hit the ship, but instead of reporting it, his curiosity took the best out of him, he hurriedly went to his backpack and took his notebook and pen out. He wondered how big the iceberg is underneath and how much of it is above the seawater. By observing, he calculated that the density of the ice is pice = 2013 Ibm/m² and floats in seawater, and by analyzing the saltiness of the water that hits his face he learned that the density of the seawater is psw = 1213 kg/m?. (2.25lbm = 1.20kg) a. What fraction of the iceberg is beneath the surface of the water? b. What fraction of the iceberg is above the surface of the water? c. Should Jack ask for Rose's help in the upcoming midterm exam?
