In Part I, the independent variable, the one that is intentionally manipulated, is
In Part II, the independent variable changes to
The dependent variable, the one you measure the response in, is the same for Parts I and II. For both parts of the
lab, the dependent variable is

learn it on the intertant so you can solve

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
