In an experiment to test for conservation of momentum, the total momentum of a system is measured before and after a collision. suppose that a graph of final momentum (pf) vs. initial momentum (pi) is made. if the hypothesis is that momentum is conserved during the collision, make a quantitative prediction of the slope and the vertical intercept of the trendline that the data should be expected to follow.

Which of the following represents a virtual image?

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
