Answer:
Originally : Level = log I / I0
Currently: Level = 10 log I / I0
Level = 10 log 600 = 10 * 2.78 = 27.8
Note the term 1 bel = 10 decibels

Answer:
x₁ = 58.09 m
Explanation:
Displacement is calculated by finding the final distance away from a point then subtracting the initial distance.
Given that initial position of object is x=25.89 m
Displacement Δx=32.2 m
Final position x₁=?
Δx = x₁-x
32.2= x₁-25.89
32.2+25.89 = x₁
58.09 m =x₁
Answer:
Reflection is simply the property of a light that rebounds or bounces back after hitting a surface.
Refraction is when the light, which passes through a surface, undergoes some changes in appearance whenever it usually passes through a medium.
