Answer:
The new intensity = 3.38 × 10⁻⁵ W/m²
Explanation:
Intensity of sound wave:
The intensity of sound is the rate of flow of flow of energy, per unit area, perpendicular to the direction of the sound wave.
Intensity (I) ∝ A²
where I = intensity, A = Amplitude.
∴ I₁/I₂ = A₁²/A²₂............................... equation 1
From the question, the amplitude increase by 30% of the initial
∴ A₂ = A₁ + 0.3A₁ = 1.3A₁, I₁ = 2.00×10⁻⁵ W/m²
∴ (2.00×10⁻⁵)/I₂ = A₁²/(1.3A₁)²
(2.00×10⁻⁵)/I₂ = 1/1.3²
making I₂ the subject of the equation
I₂ = (2.00 × 10⁻⁵)×1.3² = 3.38 × 10⁻⁵ W/m₂
The new intensity = 3.38 × 10⁻⁵ W/m²
Answer:
R = 11.8 ohms
Explanation:
Formula
R = R_ref[1 + a(T - T_ref)]
Givens
- R_ref = 10 ohms
- T_ref = 20oC
- T = 65oC
- a = 0.004
- R = resistance at 65oC = ???
Solution
R = 10*[1 + 0.004(65 - 20)]
R = 10*[1 + 0.004(45)]
R = 10*[1 + 0.18]
R = 10*(1.18)
R = 11.8 ohms
Be sure you understand not to add the 1 and 0.004 together. You don't get 1.004 at any point of the solution. If you do, you won't know what to do (exactly) with the 45.
