Calcular la longitud de onda, en nm, de una línea del espectro del átomo de hidrógeno
si el electrón sufre una transición del estado n=3 al n=2.

50 inches should be the resultant vector

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
