In the mass-spring-dashpot system, suppose we have the equation . What values of c is the system overdamped? 

In the mass-spring-dashpot system, where x(t) represents the position function of the mass: for which type of motion does x(t) approach the equilibrium position (0) as time goes to infinity?

in the differential equation: y” +py=0, what needs to be true about p to ensure the general solution takes the form 

Ester and amide local anesthetics are excreted by the kidneys.

Ester and amide local anesthetics are metabolized by the liver.

Ester anesthetics carry an allergic reaction risk because they metabolize into para-aminobenzoic acid.

During surgery, general anesthetics maintain patients at:
