A 10L helium balloon at a pressure of 2 bar at 27C. some O2 is now in balloon and final volume is made 30L. the pressure also fell to 1 bar at same temperature. the partial pressure of O2 at end is?
#quest. While music is on you will try to oppose the two ear phone pieces to attract.
Q. (a) Determine the'effective focal length' of the grouping of the two lenses in Exercise 9.10 if they are placed 8.0 cm a part with their principal axes coincident. Performed t
mass=volume * density.By using this formula we can find the mass of sphere. Volume of sphere=(4/3)pi*r^3 V=(4/3)*3.14*(1*10^-2)^3=4.187*10^-6 Mass=(4.187*10^-6)*900=3768*10^-6kg
Focal length of convex lens is 0.1 m. A liquid lens is formed between a plane surface and one face of this lens of radius of curvature 0.12m. The converging combination formed is f

The force applied at A is P30 Newton's, and P31 and P32 are dimensions in mm. A mechanic uses his left hand to support the wrench at point B. Determine the upward force required a
Stefan-Boltzmann law (Stefan, L. Boltzmann): The radiated power P (it is rate of emission of electromagnetic energy) of hot body is proportional to the radiating surface area,
Magnetism: Everyone has seen and handled a magnet in the form of a straight or horseshoe-shaped bar of steel or steel-alloy. The magnet was originally a piece of steel befor
How long does it take for the water to reach the boiling point? An iron boiler of mass 230 kg contains 830 kg of water at 18C. A heater supplies energy at the rate of 52,000 kj/
p1v1=p2v2 let partial pressure of helium in 30L be P then p1*30=2*10 p1=20/30 bar=2/3bar partial pressure of O2=p2 p1+p2=1bar partial pressure of O2=1/3 bar
p1v1=p2v2
let partial pressure of helium in 30L be P
then p1*30=2*10
p1=20/30 bar=2/3bar
partial pressure of O2=p2
p1+p2=1bar
partial pressure of O2=1/3 bar
