D. absolute magnitude and apparent magnitude
A landfill liner, or compostie liner, is intened to be a low permeable barrier, which is laid down under engineered landfill sites.
I believe its A.
Answer:the correct answer is 1.0* 10^-7 mol/L
Explanation:
Answer:
Explanation:
Total mechanical energy = 1/2 m ω²A² where ω is angular frequency and A is amplitude .
Given
1/2 m ω²A² = 5.46
ω²A² = 2 x 5.6 / m
= 2 x 5.6 / .325
= 34.46
ωA = 5.87
maximum speed = ωA = 5.87 m /s
B )
angular frequency = 2π / T , T is period of oscillation .
= 2 x 3.14 / .22
= 28.54 s⁻¹
ω = 
k is force constant and m is mass
k = 264.72 N/m
C)
ωA = 5.87
28.54 X A = 5.87
A = .2056 m
= 20.56 cm .
Answer:
The mass of the air to produce the work
m = 8.034 kg
Explanation:
Using the equation of work and energy in the system can find the mass of air needed to produce that work
T₁ = 273 °K + 257 ° C
T₁ = 530 °K , c₁ = 0.718
Eₙ - E₀ = Δ E system
- W₀ = ΔU
- W₀ = m * (u₂ - u₁)
T₂ = T₁ * (P₂ / P₁) ⁰²⁸⁶
T₂ = 530 ° K * (100 kPa / 400 kPa )⁰²⁸⁶
T₂ = 356.66 ° K
W₀ = m * c₁ * ( T₁ - T₂)
m = W₀ / [ c₁ * ( T₁ - T₂) ]
m = 1000 kJ / 0.718 * ( 530 - 356.66) ° K
m = 8.034 kg
