Chemistry pressure

WebPressure is the force applied by one object on the another. Force applied on the object is perpendicular to the surface of the object per unit area. It is represented by P. The pressure is articulated as force per unit area articulated as P = F/A Where, F = Force applied by the body (N) A = Total area of the object (m 2) WebApr 11, 2024 · Predation pressure and herbivory exert cascading effects on coral reef health and stability. However, the extent of these cascading effects can vary considerably across space and time. This variability is likely a result of the complex interactions between coral reefs’ biotic and abiotic dimensions. A major biological component that has been …
