The hall effect can be used to determine the density of mobile electrons in a conductor. a thin strip of the material being investigated is immersed in a magnetic field and oriented so that its surface is perpendicular to the field. in a particular measurement, the magnetic field strength was 0.875 t, the strip was 0.102 mm thick, the current along the strip was 3.89 a, and the hall voltage between the strip's edges was 1.59 mv. find the density of mobile electrons in the material.

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
