o surfaces, A and B has a temperature of 4500 K and different spectral ssivity as shown in Figure 3.1. By assuming Stefan Boltzmann constant is 7x 10* W/m-K, determine: the average emissivity for each surface, emissive power for each surface, wavelength of surface A at which spectral emissive power will be a maximum, and which surface is more suitable as a solar absorber? Justify your answer.

Hello, I was just wondering how you find hte angle of the blocks to 45 degrees? Thank you!

Problem- Cargo ships can cause a lot of air pollution.Solution-  to use nuclear powered ships since they hold a lot of energy and can travel for long distances. How it will work is that it will need a nuclear reactor at the bottom of the boat to heat up the water and then turn it to electricity to power the boat. The boat will be made out of graphene which is a tough material to avoid any leaks in the boat. It will also contain many control rods because nuclear power is so powerful that it can create to much energy to handle. With control rods, you can slow down this process and keep it in a controlled manner. Since cargo ships are already is the ocean, there will be no need for any extra materials to make it work. -Do you think this will work? Why/Why not?  -What do you think is wrong with it/ How can this be improved? Please send this to someone else I need to record 50 responses for a science project. Thank you!
