Student 2 is correct about everything. Since both rockets will have the same maximum vertical displacement, I predict that it will take both rockets the same amount of time to reach the ground.". it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. 2. iii. For many folks, the word "literature" conjures up memories of high school English class reading lists. Therefore, to conduct experiment based on effect of a net force , to apply net force on the object two other quantities should be measured in each trial of the experiment is given by velocity and time. Two measurements need to know while conducting trail experiments are velocity and time. Confounding bias is a type of bias that is as a result of an external factor affecting the relationship or association between a variable or subject that is being studied and its outcome.
