Hurry I don’t have a lot of time! It’s past due to :( Instructions: (part 1)elaborate about how the density of other liquids that can affect properties of other liquids. And possible errors please look at all the images!
(Part 2) elaborate changes of the experiment ( density of other liquids) and other types of experiments that can be conducted relating to density of liquids and how it affects properties of other liquids.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
