If you are still wanting to check your understanding of density, recall that it's defined as a ratio; amount of mass in a given volume. Density is mass (what units?) per volume (what units?). Write that down as a fraction (ratio). Now ask yourself: force more stuff into a fixed volume (box, bottle whatever), does density of the stuff go up down or stay same? Force same amount of stuff into a smaller volume - density up, down, same? Etc. Google the concept, or see Question 3 The Earth’s inner and outer core regions are known to be respectively: Response Feedback: Yes, good, however Earth's interior is a huge subject. Some basic can be learned from these three short resources are Question 4 The value 3.5 x 10 4 kilometers (also written as 3.5 x 10^4) without power-of-ten notation is [a] (write in the number only!). The value that is 2 orders of magnitude smaller is [b] (a number only), and the value that is twice as big is written using power-of-ten notation as [c] (a number written using power-of-ten notation).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
