Apply the combined gas law
PV/T = const.
P = pressure, V = volume, T = temperature, PV/T must stay constant.
Initial PVT values:
P = 1atm, V = 8.0L, T = 20.0°C = 293.15K
Final PVT values:
P = ?, V = 1.0L, T = 10.0°C = 283.15K
Set the PV/T expression for the initial and final PVT values equal to each other and solve for the final P:
1(8.0)/293.15 = P(1.0)/283.15
P = 7.7atm
The formula of the kinetic energy is:
where m is a mass of the object, v is speed of the object at the moment of time. So we have:
The answer is
2000 Joules.
Explanation:
ummm I believe it's frequency
Answer:
Explanation:
P = Acoustic power = 63 µW
r = Distance to the sound source = 210 m
Acoustic power
Threshold intensity =
Ratio
Ratio of the acoustic intensity produced by the juvenile howler to the reference intensity is 113.68
