An experiment with control is set to ensure that the response is the result of the independent variables in the study and not the result of any other source of variability.Control involves making sure that all participants in an experiment are treated equally, and that they are exposed to the. use the actual choice in their answer lol, As of December 2021 the answer that GR and J give are still correct, Why are there arguments on a school answer website I really dont understand like just get your answers and leave is arguing helping u get good grades? We have to identify which of the given options are correct. In each trial of the experiment, the students will apply a net force on the object. If the experimental units are people, they are called subjects or participants. This is a group of students. A -13.3 cm Its purpose is to make the conditions the same for all groups involved in an experiment and to be able to differentiate the response from just receiving treatment from the one related to the effectiveness of the treatment itself.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. Student 1: RocketYwill have a smaller maximum vertical displacement than rocketX, although it is launched upward with the same speed as rocketXand has more kinetic energy than rocketX. This answer is predicated on two assumptions - 1) we can neglect air resistance (stated in the question) on both the upward and downward paths, and 2) the rockets are in free-fall (not propelled) after launch. State the question that the experiment intends to answer. Include unit of measure, accuracy of measure, and type of, A. This is a variable that affects the outcomes of an experiment, but is not of particular interest for the experiment. 4.0, 1. a.
