The Fitzhugh-Nagumo model for the electrical impulse in a neuron states that, in the absence of relaxation effects, the electrical potential in a neuron v (t) obeys the differential equation dv dt =

A squirrel runs along an overhead telephone wire that stretches from the top of one pole to the next. It is initially at position xi=3.37 mxi=3.37 m, as measured from the center of the wire segment. It then undergoes a displacement of Δx=-6.

Two persons are applying forces on two opposite sides of a moving cart. The cart still moves with the same speed in the same direction. What do you infer about the magnitudes and direction of the forces applied?

SI unit of mass and gravity
