1. ### Reason for Velocity

And in a frictionless environment after a force is applied and then removed you have velocity. "a body in motion tends to stay in motion unless acted upon by an outside force." ... "an object at rest tends to remain at rest unless acted upon by an outside force." So you have velocity because at...
2. ### Ridiculously simple Pressure question

You cannot compress NO2 enough to liquify it. As you compress it heat is generated. You are not super-cooling your engine either. If you were getting frost on the outside of your cylinder head then that might be a consideration. Since you are running at 14000 rpm there may be a geometrically...
3. ### Nikola Tesla's Dynamic Theory of Gravity

Back to the topic..... Tesla discovered AC current, the AC motor, AC generator, radio, and fully demonstrated a modulation device that caused a small earthquake in Brookland. As to why there is no written material, the fact that the FBI confiscated all of his paperwork upon his death is a...
4. ### Ridiculously simple Pressure question

As you add more nitrous you have to add more fuel. The oxygen is released as it heated in the process of combustion. It is very easy to lean the mixture to the point that you lose power - which is what I believe you are encountering. There is too much heat in the engine to re-liquify NO2 so that...
5. ### Why don't electronics care if it's DC or AC current?

An incandescent light turns on and off 120 times a second (the polarity reverses at double the operating frequency. The filiment doesn't have time to cool off so we don't "see" the flicker. In electronics (like your computer) the power supply converts the AC to DC so the electronics can do their...
6. ### Parabolic Motion

A recursive trajectory calculation is fairly easy to setup using the time gradiant and the acceleration of gravity. Depending on initial velocities and the drag coefficient of the object you can very accurately compute the path. I did this for an external ballistics program in C back when DOS...
7. ### Contact sparks

The circuit that you are desribing sounds like an ignition source for a flammable or explosive device. I won't help with that - sorry Paul
8. ### Calculate water pressure coming out of a pipe

Why not just calculate the "Head" pressure and use that? If you know how high above the outlet the top of the water is then using the the weight of a 1 square inch column of water that high gives you the PSI of the water with the pipe shut off from flow (static or "head" pressure). There are...
9. ### Contact sparks

If you want to design a circuit in which the spark jumps a gap it has to be either alternating current or pulsed DC at very high voltages. Straight DC will not jump a gap, it has to be initiated with the conductors coming into contact.
10. ### Bypass Capacitors

Mearvk, Capacitors will not store AC current. In AC circuits a capacitor acts more like a filter resistor than a buffer or storage device. In AC circuits the capacitor can be used to change the phase between voltage and current by 90 degrees. (an inductor can be used to bring it back into phase)
11. ### Rest Mass of Photon.

Both space and time are affected by massive objects so it stands to reason that space/time would be affected by the black hole. The speed of the photon and its energy are the cause of its emission. After it is emitted Its speed and energy levels are constant due to its velocity.
12. ### What happens to you if you get pulled into a black hole?

Jimmy, the oceans are not in freefall, but I am here for another reason: I am going to attempt this one last time. I will not be sticking around for comments but you can say or do whatever you want. Since, at the black hole, we are talking about a stretching of time/space I thought I would...
13. ### What happens to you if you get pulled into a black hole?

If you feel the need to hold on to the Newtonian concept of gravity as a force then fine. There are still people who believe that the world is flat. Maybe you could have a party with them. Mass bends space/time. Gravity as a force does not exist. There is no instance where space/time curvature...
14. ### What happens to you if you get pulled into a black hole?

Jimmy, The tides are also generated by the curvature of space/time. Just as a ball that is thrown into the air is following the curvature of space/time back to the Earth. Gravity is not a force, it is an effect that we perceive from the curvature and velocity of the time/space around us. Paul
15. ### What happens to you if you get pulled into a black hole?

You have to accept that light has no mass - right? If light has no mass and it is curved around a massive object then it cannot be a force acting upon a massless object - it has to be bent space/time like Einstein set forth in GR. It can't be both. Gravity either exists as a force or it exists...
