You need to produce a Ci-Ni alloy having minimum yield strength of 20,000psi, a minimum tensile strength of 60,000 psi, and a minimum % elongation of 20%. What is the best possible composition for the Cu-Ni based on these specifications.

(The objective paragraph should extend and mention the specific point to reach the goal) the report talking about system ventilation.. i need a paragraph about this about 4 lines Birefly

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!

why is the actual weight is lower than the theoretical weight
