London dispersion forces are a type of intermolecular force. They are relatively weak. They are also called induce-dipole induce-dipole interactions. 1  Present in non-polar molecules.  Due to non-systematic electron distribution where one molecule induces a dipole on another molecule.
Pressure at which a blood vessel collapses and blood flow stops. Laplaceâs Law. Force acting on blood vessel wall is proportional to diameter of the vessel times blood pressure. Measurement of BP. Blood pressure cuff is inflated above systolic pressure, occluding the artery.ressure at which a blood vessel collapses and blood flow stops. Laplaceâs Law.
