Spin (physics) discrete angular momenta despite having no orbital angular momentum. In some ways, spin is like a vector quantity; it has a definite magnitude, and it has a "direction" (but quantization makes this "direction" different from the direction of an ordinary vector). All elementary particles of a given kind have the same magnitude of spin angular momentum, which is indicated by assigning the particle a spin quantum number. The SI unit of spin is the (N·m·s) or (kg·m·s), just as with classical angular momentum. In practice, spin is given as a dimensionless spin quantum number by dividing the spin angular momentum
AD–AS model raw materials. These factors shift short-run curves "exclusively". Changes in the quantity and quality of labour and capital affect both long-run and short-run supply curves. A greater quantity of labour or capital corresponds to a lower price for both. A greater quality in labour or capital corresponds to a greater output per worker or machine. The long-run aggregate supply curve of the classical model is affected by events that affect the potential output of the economy. Factors revolve around changes in the quality and quantity of factors of production. Keynesian Case: If there is a fiscal expansion i.e. there is
