True/False: Conducting an experiment is the process where researchers manipulate an explanatory variable to define treatments, which are randomly assigned to experimental units or subjects, to then compare the responses of the different groups to the treatments received. As the rocket The rocket then descends vertically downward until it reaches the ground at timet2. A _________ variable is a variable that is related to the explanatory variable, and it also affects the response variable, making it difficult to determine which one of the two is really causing the response.

List some sources of bias in experiments. The __________ are the different levels of a factor, or combinations of levels, in the case when two or more factors are considered, that an experimental unit is assigned. E0 = Emax ==> K = P ==> (1/2) m v02 = mghmax ==> mass can be canceled from both sides of the equation, so the maximum height is independent of the mass of the rockets and depends only on the initial velocity and acceleration due to gravity, hmax = v02 / (2g). The rocket continues upward until it reaches its maximum height at time t1. They are part of our daily lives, and they play an important role in learning about our environment.
