Explanation: Let's say I have something generating a frequency of 60hz. If I pulse that frequency on and off, 10 times a second, does that amplify the distance that wave will travel through space? Let's assume the medium it is traveling through is consistent for the moment. If the 60hz...

Thanks for the feedback. It's not for electronics cooling. It's an idea for compressing air. There would be air in the tube, the idea is to charge the air in the tube, then repel it into the balloon. If the tube was small in diameter, 1/4 inch, and there was one electrode at negative and one...

Hey guys, I am trying out an idea. I want to see if I can make an electrostatic fluid accelerator inflate a balloon. Attached is an image of a concept I came up with that works a little differently. Before I dive in, I was wondering if anyone on the forum could tell me if my concept might or...

True. I would need some big caps, it's about 10000 watts to power the motor how we want.

Does anyone of a transformer that can step up 120vac to 460vac? Or do I need to use two transformers and step it up twice? It is powering a 10hp 460vac 3phase ac motor. Thanks.

I know the accelration due to gravity. I know the weight of the car. I know how long it is accelerating for, time in seconds, and I know the circumference of the wheels. I do not know velocity or acceleration of the car. But I do have a minimum and a maximum value for velocity of the car. So the...

What if only know the length of one side and only angle of the right angle? Which is 90 degrees. I'm not sure how to find it don't know one of the other angles.

Hey guys, Is there an equation for finding the acceleration perpendicular to gravity?

Hi, thanks for the reply. It all makes sense, except c, the numerical constant, how do I determine that? by experimentation or a material constant?

Hey Guys, I have tough dynamics question. I wasn't sure if this is the best place to post it, so if it isn't please let me know. I thought it might be because I couldn't find anything about it anywhere. So here goes. If one had 10 inch long hose, 1" in diameter, filled with some incompressible...

Thanks Duck, and Lsos for the replies. They make a lot of sense. I am trying to get a good grasp on this stuff.

Hey guys, sorry if this is wrong place to post this. If it is let me and I will try and find the right place. It was the only category where I saw something about energy and physics. This is also probably a basic question but I hope you don't mind me asking. Let's say you have an electro...

Also, how do they calculate the voltage? I think my understanding of distance in parallel plate caps is making it hard for me to understand this. Thanks. SM

Hey guys, I have another quick question. How do you calculate the potential charge, in coulombs, of an electret? I can't find that one anywhere. Thanks again. SM
