Sometimes in the same direction but most of them go in the opposite direction
I'm not that smart but I think it is c I really hope It helps
Refractive Index is a ratio of two similar physical quantity which is dimension less
refractive index = sin I / sin r
therefore it doesn't have a unit.
Answer:
≈ 0.144 m
Explanation:
Density is mass divided by volume:
D = M / V
Solving for volume:
V = M / D
Given M = 1.2 kg and D = 400 kg/m³:
V = 1.2 kg / (400 kg/m³)
V = 0.003 m³
Volume of a cube is the side length cubed:
V = s³
Therefore:
s³ = 0.003 m³
s ≈ 0.144 m
Round as needed.
