I have tanks at different pressures of CO2 and methane. I want to mix them through flow regulators (not pressure regulators) in various proportions. The flow regulators are simple "calibrated bead in tube" type (called "Flow Raters" manufactured by Dwyer). If flow from both tanks is maintained at some level is it possible for gas from the higher-pressure container to enter (backwards through the other 'flow rater') the lower-pressure container? Pressure in both cylinders is similar, but not identical. I would establish flow from the low pressure cylinder first, then the high-pressure cylinder, and shut off the high pressure cylinder first. Again, I can regulate flow rate (in scfh) well enough for my purposes, but have no way of regulating pressure.

The electrons that produce the picture in a
TV set are accelerated by a very large electric
force as they pass through a small region in
the neck of the picture tube. This region is
1.7 cm in length, and the electrons enter with
a speed of 100000 m/s and leave with a speed
of 1.5 * 10^8 m/s.
What is their acceleration over this 1.7 cm
length? Answer in units of m/s2.

part 2
How long is the electron in the accelerating
region? Answer in units of s.

I need to know that, and a couple other answers to questions like finding time from acceleration and distance, and other things. Thanks.

E = mc2 does not describe the value of "c" for what it is, but what it does - like the current equation for the force of gravity. But, when the value of "c" is equal to that of "h" in form of energy, then the equation for a gravitational field "c2 = E/m" makes sense, right?

I think its either black or grey,and sometimes they rub them together and put them on the patients chest and somehow it revives them.My question is,what is that instrument called,and how does it make that person's heart start beating again?

Most people know that most objects can change from a solids to a liquid to a gas and back. But then there is plasma. Can substances like water change into a plasma or some other phase of matter? Are there any other phases other than the four I have listed?

Okay, I've been tought that an atom had protons, electrons, and neutrons, and quarks and stuff inside. But why? Why do atoms need to have them? More importantly, why are electrons negatively charged, and why are protons positive? Just because they are? There has to be a more correct answer than that.

E.g. A machine which can see into the future rings a bell 20 seconds before you clap yor hands.

Is it possible to hear the bell ring and then not clap your hands (i.e. you were prepared to clap your hands but once you heared the bell you changed your mind) , or will the bell never ring, because it can see into the future that you are not prepared to clap your hands?

this gave me a headache!

i got thinking about different dimensions and the theory of alternate universes and it got me thinking we think there are an infinite number of dimensions and an infinite number of possible universes whithin those dimensions and if that is right does that mean that there are non-universes, absolute nothingness?

3,move them forward until the edges of the coins touch, with your tongue in between
4. Now rinse your mouth with strong salt water, a teaspoonful of salt to a glass of water.
5.Repeat the procedure as in Step 2.

Results
1. What happened when the coins touched the first time?
2. What happened when the coins touched the second time?
