Multiple choice physics measurements and units kinds of units fundamental quantities standardized measurement $S.I$unit of conductivity isĀ $siemens / meter$ $siemens \times meter$ $meter \times siemens$ ${m}^{2}/ohm$ Reveal answer Fill a bubble to check yourself A Correct answer Explanation Conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter $(S/m)$
Multiple choice physics measurement of physical quantities kinds of units fundamental quantities standardized measurement Which expression has the same SI base units as pressure? $\dfrac{force}{length\times speed}$ $\dfrac{force}{length\times time}$ $\dfrac{mass}{length\times (time)^2}$ $\dfrac{mass\times (time)^2}{length}$ Reveal answer Fill a bubble to check yourself C Correct answer Explanation Pressure is force per unit area.$P = \dfrac FA=\dfrac {MLT^{-2}}{L^2}=\dfrac M{LT^2}$
