Expressed in cylindrical coords. use the analogy among the equations that determine vector potential and magnetic field: ∇"⃗ ∙ �"⃗ = 0 ∇"⃗ × �"⃗ = �)�⃗ �⃗ = 0 ∇"⃗ × �⃗ = �"⃗ to find the vector potential: a) for � ≤ � b) for � >

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
