A metal rod with a 4 millimeter radius is held in tension. When a load of 15,700 N is introduced, a reduction of 5E-3 millimeter in diameter is recorded. What would be the Poisson's ratio for this material if its modulus of elasticity is 140 GPa

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?

Elements that have one valence electron and are very reactive are called
