Answer:
The vapor pressure is 748.77 torr
Explanation:
Using Clausius-Clapeyron equation:
where;
T₁ is the initial temperature = 85.0°F = 302.5 K
T₂ is the final temperature = 100 °C = 373 K
P₂ is the final pressure = 760 torr
P₁ is the initial pressure = vapor pressure = ?
R is gas constant = 8.314 J/K.mol
ΔHvap is the heat of vaporization of water = 40.7 kJ/mol
4.895(0.00331 - 0.00268) = 0.01489
= 1.015
P₁ = (760 torr)/(1.015) = 748.77 torr
Therefore, the vapor pressure is 748.77 torr
Finally, the amount of increased volume<span> that is achieved by an increase in </span>amplitude<span>is also affected by the frequency. So, turning the </span>amplitude<span> level in the mid-range sound from the previous example will not have the same proportional effect on loudness as the bass sound.</span>
Answer:
w = 0.886 rad / s
Explanation:
Angular and linear variables are related
a = α r
where a is the linear acceleration, α the angular acceleration and r the radius of gyration
α = a / r
the angular velocity we can find it
w² = w₀² + 2 α θ
the initial angular velocity is zero, the angles to be horizontal is
θ = π/ 2 rad
we substitute
w = √ 2 a / r θ
we calculate
w = √ (2 3/12 π/2)
w = 0.886 rad / s
