Answer:
3.9 atm
Explanation:
Ideal gas law states:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is universal gas constant,
and T is absolute temperature.
The volume of the tank is constant, so we can say:
V₁ = V₂
Using ideal gas law to write in terms of P, n, R, and T:
n₁ R T₁ / P₁ = n₂ R T₂ / P₂
n₁ T₁ / P₁ = n₂ T₂ / P₂
Initially:
P₁ = 9.8 atm
T₁ = 29.0°C = 302.15 K
n₁ = n
Afterwards:
P₂ = P
T₂ = 83.0°C = 356.15 K
n₂ = n/3
Substituting:
n (302.15 K) / (9.8 atm) = (n/3) (356.15 K) / P
(302.15 K) / (9.8 atm) = (1/3) (356.15 K) / P
P = 3.85 atm
Rounding to 2 significant figures, P = 3.9 atm.
At 350 K the approximate volume is 83 dB.
The Volume is much louder at 900 K
Answer:
The answer is true, when performing Tai Chi, The breathing technique utilized is called “Belly Breathing”
Explanation:
Let <em>v</em> be the dog's initial velocity. Then
(13.5 m/s)^2 - <em>v</em> ^2 = 2 (1.50 m/s^2) (49.3 m)
==> <em>v</em> ^2 = (13.5 m/s)^2 - 2 (1.50 m/s^2) (49.3 m)
==> <em>v</em> = √((13.5 m/s)^2 - 2 (1.50 m/s^2) (49.3 m))
==> <em>v</em> ≈ 5.86 m/s
