Answer:
Explanation:
We can solve the problem by using Snell's law:
where
n1 = 1.33 is the index of refraction of the first medium (water)
n2 = 1.00 is the index of refraction of the second medium (air)
is the angle of incidence of the wave in water
is the angle of refraction of the wave in air
Solving for the angle of refraction,
Answer:
The marble as lost energy due to gravity, air resistance (if there is air), and the centripetal force when going around that loop.
Explanation:
Also a little in heat but that rly doesnt matter
yes that's true 6g is larger
Answer:
The answer is B
Explanation: Greenhouse gases must be able to change their vibrational state in order to absorb infrared radiation or heat. SO therefore helium is not one of them.
Hope this helps:)
