Answer:
n = 1.523
Explanation:
Snell's law
1.273sin32.89 = nsin26.99
Electricity is not apart of it
Answer:
Explanation:
The PE equation for a mass/spring system is
Δx² and filling in:
and
so
k = 26000 N/m
If the displacement from equilibrium changes more, the PE needed to compress it will also change.
gives us that
PE = 520J
