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
Any form of succession will change the environment. That's why there is succession in the first place. With each stage of succession there will be greater biodiversity that results in a change in abiotic factors like soil composition, shade, humidity, weather, exposure, etc
Traveling at any point on a curve, the force and the acceleration are toward
the center of the circle that the curve is part of. On a perfectly circular path,
the force and acceleration are always toward the center of the circle.
Answer:
340000
Explanation:
The answer is 340000 because there will be six digits, as it is one digit followed by five zeroes, but one of the zeroes is a 4 because of the 4 in 3.4. 3.4x10^5 is 340000 in standard form.
