Answer:
Angle of Refraction = 28.9 degrees
Explanation:
<u><em>We'll use Snell's law for this. It's mathematical form is:</em></u>
=> 
Where 
=> 
and 
are the refractive indexes of the air and water respectively.
<u><em>Solution:</em></u>
=> 1 * sin (40) = 1.33 * sin(
)
=> sin = 
=> sin = 0.4821
=> = 28.9 degrees
Answer:
Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
Answer:
Inhibit the flow of electrons
Explanation:
An electric current usually consists of electrons moving through a wire.
An insulator prevents the flow of an electric current, so it inhibits the flow of electrons.
