Three equal masses of 3.4 kg each are located at three corners of a square of edge length 2.2 m. use g = 6.67259 × 10−11 n m2 /kg2 . find the magnitude of the gravitational field at the fourth corner due to these masses. answer in units of n/kg.

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.
