Concept explainers
(a)
Interpretation: For small extensions of the chain, it has to be shown that the restoring force is equal to the given expression.
Concept Introduction: The restoring force refers to a force that creates equilibrium. When the system is disturbed from the equilibrium, the function of restoring force is to bring back the equilibrium to the system. The restoring force is given by the formula,
(b)
Interpretation: Whether the variation of the restoring force with respect to the chain extension is part (a) is different from the Hooke’s law or not has to be explained.
Concept Introduction: The restoring force refers to a force that creates equilibrium. When the system is disturbed from the equilibrium, the function of restoring force is to bring back the equilibrium to the system. The restoring force is given by the formula,

- Hi I need help on the question provided in the image.arrow_forwardDraw a reasonable mechanism for the following reaction:arrow_forwardDraw the mechanism for the following reaction: CH3 CH3 Et-OH Et Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron-flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. H± EXP.
