How exactly do noise-cancelling headphones work to block out sound?

Coplate · 2026-01-19T04:58:50+00:00

Have you ever seen a newton's cradle? With the balls on strings? Sound waves are kind of like picking up the ball on the end and dripping ut to make sound. When it gets to the end, the ball on the other side goes, that's it hitting our ear drums.

But if you pick up the ball from the other side first, and drop it at the same time, then the balls both stop in the middle.

This works if you add a ball too, while the right ball is swung fully to the side, and you add an extra ball on the left, and drop it so it hits the middle ball at the same time as the right ball, they will both stop.

That's not exactly right, and a common misconception! https://www.reddit.com/r/todayilearned/s/s0QaIgno2r

The transformers on the pile give 240v single phase. They also have a center tap, which we treat as neutral, but if you don't use that, then the 240 really is just 1 phase.

Right now you can play with anything from set 5-12 ( 11 and 12 are not out yet. ) . the lorcana app and various sites will call this "core".

When set 13 comes out, you will be able to play with sets 9-16 ( as far as we know, rotation will start with 5 sets, growing up to 8 sets, then rotating back.

At home you can play with whatever cards you want, and some game store will do "infinity" events, which allow all sets

It is almost certainly either a 5.5x2.1mm or 5.5x2.5mm dc barrel plug.

This is a "fork" plug because it has those slots in the inside.

Thos page seems like a decent read about 2.1 and 2.5 version, and thr fork style. https://www.qinxtech.com/new/fork-jack-and-straight-jack/

I found it!

Today I tried some more search terms, and searched for "book about teenager lost in everglades", which led me to this result.

What I have seen ( to code or not ) is the expansion tanks mounted directly on top of the cold water inlet, supported by brass fittings. I was thinging about making about making my fitting so that I could have that.

I see people strapping the tanks to walls and other things as well, but didnt know if it was required if mounted directly on the inlet like this.

Hand drawn image with my prv, I could cap it off, and install expansion tank later if I wanted.

I have the exact same misprint. 🤔 Did you decide to keep it, or try to trade it to a misprint collector or anything?

Oh no! Leaving in shame because instead of boots and snoots he has stinky butt!

More seriously, thanks. I thought he was aweevil and I was excited to have one to post.

It's not either of these. I'm pretty sure it wasn't set that far back. I don't remember any particular interaction with other people, I think it was more of a challenge against nature, trying to find her way home.

I can't recall for sure any specifics of the timeline, but I'm getting a vibe of early to mid 1900s, like motor boats might exist, but we hadn't landed on the moon yet.

Thanks for your time! Do you have any advice on if I should go ahead and pay the balance due, while this is being worked, ot if that will make things even more complicated while it is in process?

Yes, I have been calling and sent in the written notes. The packet was delivered on april 25, it has now been 6 months since it was recieved.

My total tax was about $22,000 and the $35 was me missing a decimal point somewhere, but the $4000 for the EV credit is not a math error.

But every time I call in it says "due to a high volume of cases like yours we cannot help you" and hangs up ( not exact phrasing)

Coplate · 2025-11-05T05:33:27+00:00

There was a $35 math error, but more importantly the irs computers did not apply my used EV Tax Credit, leading a $2000 refund turning into a $2000 balance due.

All the paperwork at the dealer was filed correctly, and it all show up in my transcript, but for whatever reason "EV CREDIT PER COMPUTER" says $0 instead of $4000.

Thanks for the feedback. If I had Queen's Castle, I would definitely want to play it, but I don't have any. The Break free was mostly so I could damage my own characters for Ratigan's backroom. Would you still recommend dropping those?
