Analyzing fluid movement necessitates separating between laminar motion and turbulence . Steady flow implies uniform velocity at each area within the fluid , while turbulence characterizes irregular and variable configurations . The principle of continuity formalizes the preservation of matter –

Thomson's Plum Pudding model, while groundbreaking for its time, faced several challenges as scientists developed a deeper understanding of atomic structure. One major limitation was its inability to explain the results of Rutherford's gold foil experiment. The model assumed that alpha particles
