where m is the mass, b is the damping coefficient, k is the spring constant, f is the force acting on the mass and x is the displacement of the mass. The effect of added mass acts in opposition to the motion of the mass, so the equation of harmonic motion is adjusted to reflect ...

This mass-spring mechanical model captures the natural behaviour of Diatoma chains well, emphasising the relevance of chain growth and entanglement for biofilm morphogenesis. The model qualitatively describes formation of intricate dome-shaped structures and of dreadlock-type streamers as observed in ...
Niño events30,31. This ENSO-driven decadal variability in CDW thickness appears to be superimposed on a centennial trend of increasing westerly wind anomalies18and an associated increase in Amundsen Sea heat content32. While influential on the wider Antarctic climate, the Southern Annular Mode (S...
A spring with a spring constant of 100 N/m completes one oscillation in 2.4 seconds. What is the mass attached to the spring? How many calories will it take to melt 75 grams of ice? What mass of copper(II) nitrate, Cu(NO_3)_2, must...
How to find the period of a pendulum How can you increase the period of a pendulum? Does angle affect the period of pendulum? How to calculate period of oscillation of a pendulum If a pendulum has a length of 5 meters, what will be the period of the pendulum?
Lithophaga lithophaga is one of the commonest bivalves in the Mediterranean Sea and is present in almost every subtidal calcareous rock. Its reproductive cycle is known only from laboratory studies. Herein, we present data on the species reproductive activities based on localised but mass synchro...
In particular, various approaches have been used to increase the Q-factor, including reduction in resonator size to the nm scale, reduction in effective mass, and optimization of anchor structure9–11. In general, dissipation of mechanical energy during oscillation deteri- orates the Q-factor. ...
individual cells versus time. The measurements were carried out in three schemes. First, the responses of an unloaded vibrating sensor (in air) was measured to determine the spring constant. Second, we measured the responses of an unloaded sensor (in media) to determine a reference resonant ...
of industrialisation. The mass balance data for Sweden are taken from Linderholmet al.45, and those of the Canadian Rockies are from Lewis and Smith46. The Northern Hemisphere temperatures are derived from Mannet al.20and the mean spring temperature departure time-series for the western Himalaya...
