Question

la persona de las fotos está separando las cargas de su cab
globo. ¿cómo lo hace?
a. la persona quita las cargas del globo.
b. la persona sostiene el globo en el aire que
tiene una carga positiva.
c. la persona se mueve hacia una
ubicación con carga del salón.
d. la persona crea fricción al mover el globo
hacia adelante y hacia atrás.

Explanation:

When a person rubs a balloon (creates friction by moving it back and forth), electrons can be transferred between the balloon and the person's hair (or other materials). This process is known as triboelectric charging. Friction is the key action here that leads to the separation of charges. Option A is incorrect as it's about removing charges (not relevant to the common "separating charges by balloon - hair interaction"). Option B is wrong because air itself (in the normal sense described here) isn't the main factor in the typical balloon - hair charge separation. Option C is not in line with the common charge separation mechanism via friction.

Answer:

D. La persona crea fricción al mover el globo hacia adelante y hacia atrás.
