Heat is flowing through a slab of material by conduction heat transfer; and the heat flux is 16500W/m^2. If the slab is 3.0 cm thick and the thermal conductivity is 18 W /(m K), what is the temperature difference across the slab?

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question
