Some more practice with tensor products. îfa8b is the tensor product of an observable a = at acting in hilbert space and bb acting hilbert space and (2) is any real-valued function, then f(a3 b) is an observable acting on ж. зно. true or false? f(a b) explicit counter-example. f(a) f(b). if true, demonstrate that it is true. if false, provide an explicit counter example.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
