Yes, the USB cable is carrying 5 (or 9/12/15/20) volts direct current. Thr job of the charging brick plugged between the USB cable and the wall is to regulate AC power down to direct current for USB

The AC side voltage/frequency doesn't matter as long as you have a wall adapter that works for that situation. The device being charged sees a USB power source and doesn't care what's driving that.
(Also note that many, but not all, common wall-plug USB power supplies are natively designed to work under both voltages. It's usually just matter of having the appropriate plug adapter to connect the pins from whatever sockets are used abroad)

Early Georgia really wanted a local government/county seat to be within about a day's journey by whatever means of travel was available at the time.
As the state grew, that meant creating a bunch of counties.

Reply to Eli5 if a phone number is 7 digits then how aren't there more people with the same number? by FrozenKyrie
North American telephone numbering plan numbers are 10 digits long including a 3 digit area code
Despite some area codes and branch prefixes being reserved, this still provides enough numbers for current needs.

Reply to ELI5: why are male to male USB-C cables not dangerous like male to male wall plugs are? by KeyStomach0
The outside shell of the connector is electrically neutral, the only points in the connector with a different voltage are inside the connector, and no properly designed device should ever supply power along a USB+c connector without verifying it can receive power
Wall plugs have two different exposed conductors an inch or so apart with a over a hundred volts AC between them

Reply to comment by Phage0070 in Eli5 why do stairwells need to be have two flights in a spiral to go up one floor when escalators can just use the one flight going straight up for the same distance? by exmxn
> An escalator can't make such turns so they need to be straight,
Side note, curved escalators can be made, but they're very expensive (I've never seen one outside of Las Vegas) and take up a huge amount of floor space in comparison

> Aren't people who use credit cards a lot more risky to the bank, in the sense that they might not have enough fund
Look at it another way, a person who for years has been able to handle having a few hundred dollars in revolving accounts, and never missed a payment, would appear as a lower risk than someone who has never had any kind of loan before.

Reply to Eli5 credit score please. by astajaznan
The general idea of a credit score is that is a numerical summary of a person's credit history.
Credit cards are among the easier ways to establish a revolving line of credit without any additional spending, so they're often discussed as ways to do exactly that.

Because the disc rotor is an easily replaced component, there's no concern about it wearing out, so disc brake pads can use more aggressive materials to increase friction between the pad and rotor.

Unless the action that changed the law included some provision for those with existing convictions, nothing.
Although asking for a pardon may be successful in such cases.

The kinds of customers who would shop at warehouse clubs generally would have no issues spending about $60/year on a membership, and these warehouse club chains generally choose locations where there is no shortage of customers
If they didn't charge for memberships, prices would have to be adjusted elsewhere to make profit for the company.

Reply to ELI5: How does airport technology, still allow people to check in and pass through TSA if Im at the wrong Terminal. by Witty_Buddy7951
The person checking IDs at the checkpoint isn't investigating which airline you're flying on, they're just checking you have a boarding pass issued for that day and that you're the same person named on the identity document.
It's the traveler's responsibility to know where they need to go, and airline staff and communications will often help.

Reply to ELI5 : How come that the biggest tech company products, like Windows OS can be cracked and used for free while apps made by small companies have a strict paywall impossible to break? by [deleted]
There's not much of a point in overly restricting the windows OS.
End users who don't want to pay for it anyone are just going to find a workaround.
It's the OEMs and corporate users where Microsoft makes their money, and who also lucrative targets for legal action if they are using it unlicensed
It's a similar strategy to how Adobe has protected their creative suite products: they rather have college students and personal enthusiasts familiar with that particular software than fight tooth and nail enforcing licensing on the average person.

The performance of the consoles isn't infinite, developers may still need to either make such a decision, or create multiple profiles and let the user select.

It would still be common for some (particularly non-visa/mc debit cards) to provide the option. Mine did back in the late 2000s.

You can't just stop supplying water to distribution pipes: that would create widespread pressure drops and consequently huge areas would be entering boil water advisory situations, and testing water after a mains pressure loss gets expensive.

Reply to ELI5 why can't you just plug in electric cars / why do you need a wall charger when it could just be built in by definetlynotaalien
A typical US household outlet can only be used for 1500 watts continuously, and that's sometimes complicated by the fact there may be other devices on that same circuit that are also drawing electricity.
1.5kw isn't a very fast charging speed for electric vehicle batteries, especially for vehicles driven every day or close to that.
A household EV charger is just a special connecter wired up to a power source rated for a higher current at 230v.

The fees are often directly a part of what the venue/artist earns, its just disguised as a fee instead of an upcharge.
Also, Livenation has a near monopoly status on many artists and large venues.
