Web14 apr. 2024 · Introduction Estimates of initiation, cessation, and relapse rates of tobacco cigarette smoking and e-cigarette use can facilitate projections of longer-term impact of their use. We aimed to derive transition rates and apply them to validate a microsimulation model of tobacco that newly incorporated e-cigarettes.

Web22 jul. 2024 · 0. Amplitude is generally not a distance as such it is not true that the amplitude is twice the wavelength for longitudinal waves. One way to convince yourself about this is to just think of a regular sound wave. The amplitude of the sound wave basically describes how dense the air is at a given point, more amplitude being related to having ... Web25 okt. 2024 · As a mechanical wave, longitudinal waves always require a medium to propagate. The medium determines how fast the wave travels from one point to the next. … WebThe longitudinal waves in an earthquake are called pressure or P-waves, and the transverse waves are called shear or S-waves.
