question 12 of 15
where are you most likely to build up enough static charge to receive a shock?
a. on a nylon carpet in a hotel by the beach
b. in a rain forest
c. on a concrete sidewalk on a dry day
d. on a nylon carpet in a dry area

Explanation:

Static charge builds up when there is friction between materials and low humidity (dry conditions). Nylon is a material that can easily gain or lose electrons (triboelectric effect). In a dry area, the charge cannot dissipate easily (unlike in a humid place like by the beach or a rain - forest). Concrete is a conductor, so charge would not build up as much as on an insulator like nylon.

Answer:

D. On a nylon carpet in a dry area
