(II) A neuron is stimulated with an electric pulse. The actionpotential is detected at a point 3.70 cm down the axon0.0052 s later. When the action potential is detected 7.20 cmfrom the point of stimulation, the time required is 0.0063 s.What is the speed of the electric pulse along the axon? (Whyare two measurements needed instead of only one?)
Dielectric Constant Of Water
Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.
Electrostatic Potential and Capacitance
An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.
