Pressure at the surface is 1 atm = 101 kPa.
Pressure at 11 m = 2.09 atm = 212 kPa.
V2 = V1*(T2 / T1)*(P1 / P2)
V2 = (8.18 cm3)*(289 K)*(212 kPa / 101 kPa)
V2 = 4962 cm3
That can't be right... What do I need to have everything converted to?
Do I convert them to the following:
T1 = 16.0ºC +...

A 1.450 kg air-track glider is attached to each end of the track by two coil springs. It takes a horizontal force of 0.700 N to displace the glider to a new equilibrium position, x= 0.290 m.
a.) Find the effective spring constant of the system.
b.) The glider is...
1. Homework Statement :
A simple pendulum has a mass of 0.25 kg and a length of 1.0 m. It is displaced through an angle of 5.0° and then released.
1. What is the maximum speed?
2. What is the maximum angular acceleration?
Answer: 0.855 rad/s2
3. What is the maximum restoring force?
Answer...
Okay. So to find pressure difference:
P = 8 * η * L * Q / pi * r4
P = 8 * (0.004 Pa*s) * (0.0407 m) * (6.5 x 10-8 m3/s) / pi * (0.000194 m)4
P = 19023 Pa
If that is correct, how do I find height from this?
