As limestone, calcium carbonate is a biogenic rock, and is more compacted than chalk. As marble, calcium carbonate is a coarse-crystalline, metamorphic rock, which is formed when chalk or limestone is recrystallised under conditions of high temperature and pressure.
Definition: A wavefunction is a function describing the probability of a particle's quantum state as a function of position, momentum, time, and/or spin. Wavefunctions are commonly denoted by the variable Ï.
Wave summation contributes to contractile force, but its primary function is to produce smooth, continuous muscle contractions by rapidly stimulating a specific number of muscle cells. The force of contraction is controlled more precisely by recruitment, also called multiple motor unit summation.
