Answer:
225,563,910 m/s
Explanation:
speed of light in water = speed of light in the air/refractive index
speed of light in water = 3.00 x 10^8 m/s/1.33
speed of light in water = 225,563,910 m/s
I think it’s b sorry if it isn’t it’s been a while since I’ve done this but it should be positive charge
<span>People with protanopia are unable to sense any ‘red’ light, people with deuteranopia do not sense ‘green’ light and people with tritanopia cannot sense ‘blue’ light.
