Frotación

Al frotar dos cuerpos eléctricamente neutros (número de electrones igual al número de protones), ambos se cargan, uno con carga positiva y el otro con carga negativa. Si se frota una barra de vidrio con un paño de seda, hay un traspaso de electrones del vidrio a la seda

Inducción

Cuando un cuerpo cargado se acerca a uno descargado sin llegar a tocarlo, las cargas en este último se reagrupan en dos regiones distintas del mismo, debido a que los electrones del cuerpo descargado son atraídos o repelidos a uno de los extremos según sea el caso; al alejarse nuevamente el cuerpo cargado desaparece ese reagrupamiento de cargas.

Contacto

En la electrización por contacto, el cuerpo conductor es puesto en contacto con otro cuya carga es nula. Aquel cuerpo que presente un exceso relativo de electrones los transferirá al otro. Al finalizar la transferencia los dos cuerpos quedan con carga de igual signo, ya que cargas iguales se repelen. Al mismo tiempo se crea una barra nuclear que impide el movimiento de partículas sub biónicas nucleares.

Answer from: Quest

1. when the tempature rises,your sweat glands and then springs into action making perspiration. some sweat evaporates with your skin taling heat with it.2.some of the blood pumped by the heart travels by your lungs to get rid of carbon dioxide and pick up oxygen.3.saliva produces by, you drinking water which saliva is 98% of. when mucus builds up in your body it also creates saliva as well as, antibacterial compunds.4.when the core body tempature drops, the shivering reflex is triggered to maintain homeostasis. for example: when you get out the pool you start to shiver because it is cold.
