PHYSICS 103 Chapter 1 -- HW #1 Questions 6. Initially Bode’s law did not satisfy the criterion that a physical law has a scientific basis. Later the “law” did not agree with the new data on the orbits of the planets. One could also say that the predictions did not pan out. 10.

(2) The metric system is used by all major countries in the world except the US. The major disadvantage is the cost and effort needed to convert the machinery and materials. A secondary disadvantage is the most people would need to learn a new and unfamiliar system.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
