A possible means for making an airplane invisible to radar is to coat the plane with an antireflective polymer. If radar waves h

Marina CMI [18]

Answer:

The thickness is $t = 0.5615 \ cm$

Explanation:

From the question we are told that

The wavelength of the of the rader waves is $\lambda = 2.92 \ cm$

The index of refraction of the polymer is $n = 1.30$

The thickness is mathematically represented as

$t = \frac{\lambda }{4 n }$

Substituting values

$t = \frac{2.92}{4 * 1.30 }$

$t = 0.5615 \ cm$

An audio engineer takes decibel readings at distances of r1 = 13 m and r2 = 24 m from a concert stage speaker during a sound che

N76 [4]

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

$\beta = 10 log(\dfrac{I}{I_0})$

I₀ = 10⁻¹² W/m²

now inserting the given values

$101= 10 log(\dfrac{I}{10^{-12}})$

$10.1= log(\dfrac{I}{10^{-12}})$

$\dfrac{I}{10^{-12}}= 10^{10.1}$

$I =10^{10.1} \times 10^{-12}$

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
