8. In A Hall Experiment, A Current Of 25 A Is Passed Through A Long Foil Of Ag, Which Is 0.1 Mm Thick And 3Mm Long. Calculate The Hall Voltage Produces Across The Width By A Flux Of 1.4 W/M2. If The Conduction Of Ag Is 6.8X10Mho/M. Estimate The Mobility And Hall Coefficient.

Ann walks 80 meters on a straight line 33 ∘ north of east starting at point 1. draw ann's path. represent ann's walk with a vector of length 80 meters. draw the vector starting at point 1. the length given in the display is in meters.

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.
