    How Large Will the Air Bubble Be When It Reaches the Surface?

    V2 = V1*(T2 / T1)*(P1 / P2) V2 = (8.18 cm^3)*(289 K / 289 K)*(212 kPa / 101 kPa) V2 = (8.18 cm^3)*(2.099 kPa) V2 = 17.17 cm^3 Correct?

    How Large Will the Air Bubble Be When It Reaches the Surface?

    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 +...

    How Large Will the Air Bubble Be When It Reaches the Surface?

    Homework Statement A scuba diver releases a 2.50-cm-diameter (spherical) bubble of air from a depth of 11 m in a lake. Assume the temperature is constant at 16.0ºC, and the air behaves as a perfect gas. How large is the bubble when it reaches the surface? Homework Equations V2 = V1*(T2...

    Spring Constant and Oscillations -

    So I got 0.0182 with my calculator in radians... Is that correct?

    Spring Constant and Oscillations -

    I changed my calculator to radians: x(t) = A sin (sqrt (k/m) * t) x(t) = (0.290) sin(sqrt (2.41 / 1.450) * 0.490T) x(t) = 0.145 m

    Spring Constant and Oscillations -

    So I did: x(t) = A sin (sqrt (k/m) * t) x(t) = (0.290) sin(sqrt (2.41 / 1.450) * 0.490T) x(t) = (0.290) sin(1.29 * 0.490T) x(t) = (0.290) sin(0.6321T) x(t) = (0.290)(0.011) x(t) = -0.00319 m Does that seem correct to you?

    Height of Blood Transfusion - ?

    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?
