Answer:
<em>The wavelength of water = 571.43 nm</em>
Explanation:
Refractive index of water = wave length of light in air/wave length of light in water
R.d = λ₁/λ₂.................. Equation 1
making λ₂ the subject of equation 1
λ₂ = λ₁/R.d...................... Equation 2
R.d = refractive index of water , λ₁ = wave length of light in air, λ₂ = wave length of light in water
<em>Given: R.d = 1.33, λ₁ = 760nm</em>
<em>Substituting these values into equation 2</em>
λ₂ = 760/1.33
<em>λ₂ = 571.43 nm</em>
<em>Therefore the wavelength of water = 571.43 nm</em>
I don’t know how to fill this out since there is no picture attached.
Because the plate doesn't have water, and it's water which is heated by the microwave
Answer:
CO2 increases in the winter
Explanation:
Answer:
B. 4 m/s
Explanation:
v=d/t
Running for 300 m at 3 m/s takes 100 seconds and running at 300 m at 6 m/s takes 50 seconds. 100 s + 50 s = 150 s (total time). Total distance is 600 m, so 600 m/ 150 s = 4 m/s.
