) del cable, medido en newtons por metro cuadrado, es determinada por la siguiente expresión:
- Fuerza axial, medida en newtons.
- Área transversal, medida en metros cuadrados.
- Diámetro, medido en metros. 
y 
, entonces:
), adimensional, se determina con esta fórmula:
- Longitud final, medida en metros.
- Longitud inicial, medida en metros.
y 
, la deformación longitudinal unitaria es:

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
