b) px^2
c) px + px^2
d) px-px^2
​

Answer 1

Explanation:

(a) Pair of corresponding angles

(b) Pair of alternate interior angles

(c) Pair of vertically opposite angles

(d) Pair of interior angles on the same side of the transversal.

Answer 2

Explanation:

Since A & B are operators rather than numbers , they don't ... where f & g are functions & c is a constant. ... (-h2/2m) d2/dx2 ↔ px. 2/(2m). Some Postulates of Quantum Mechanics
