You see its position before and then its position after.
Answer:
because there isn't any gravity there
The phase is called 3rd quarter.
Hope this helps:)
Answer
given,
Distance for decibel reading
r₁ = 13 m
r₂ = 24 m
When the engineer is at r₁ reading is β₁ = 101 dB
now, Calculating the Intensity at r₁
Using formula

I₀ = 10⁻¹² W/m²
now inserting the given values




I = 0.01258 W/m²
now, calculating power at r₁
P₁ = I₁ A₁
P₁ = 0.01258 x 4 π r²
P₁ = 0.01258 x 4 π x 13²
P₁ = 26.72 W
The net force is 12 N to the left.
