<span>c. They help discard some myths about objects in space.
When we learn something new, then we know more stuff,
and that helps us avoid ignorance and superstition.
The REAL question is:

One electron Volt (eV) is equal to 1.6 x 10^-19 Joules. Therefore, 10 eV is equal to 1.6 x 10^-18 Joules. In order to produce 20 Joules of energy from 10 eV photons, we would require 20 x 1/(1.6 x 10^-18) = 1.25 x 10^19 particles. This demonstrates that in the world of particle physics, the Joule is a massive energy unit relative to the commonly used electron Volt.
They're most likely to be used in a house because if you turn on a switch in ur house the rest of them stay off they don't turn on
