What have you found so far? If you type that into Google, one of the resulting category tabs will be "videos"... :smile:

OK, then proceed as suggested by @berkeman and then check out the search results one by one until you find the videos that match what your are looking for.

I think you may have suffered from the fact that the term Plasma is taken by search engines to imply you want to buy something that uses plasma. (That's what they make their money with.) You need to get past their defences.

You need to choose a suitable extra term if you want some Physics content. I tried Low pressure plasma formation" and that got me past the sales section into things that you may want. Web searching is all about asking the right question and that 's a skill that takes time and determination to acquire.

Sorry if that sounds smug but it's true. Think of it as an adventure game where you have to ask the dragon the right question before you get to the gold. Good luck.

No more from the OP.
 
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
This has been discussed many times on PF, and will likely come up again, so the video might come handy.
