Questions you'd like answering, regardless of how trivial they may seem

The bits of it I've used , have been Duelled , heavy ,fast moving traffic

Not condoning it in anyway, but HGV drivers do have a better view sat high up there, maybe the fog was less dense, if only a matter of feet.

This definitely happens.

We've all seen fog that is only a few feet off the ground - just look across fields around dawn. Not much stretch that on certain occasions it might reach upto car drivers' eye-level, but not upto the HGV drivers.

Were you riding on it? 😳

I am considering buying an upright piano. If I get an analogue piano, could I use a digital keyboard to tune it?

Not on yet Nelly,! I wouldn't

Wouldn't be much good riding/ driving a piano down the A34 , unless the traffic cops ask them to accompany them to the station ...., diddly diddly dum, tsk! tsk!

I thank y'all.

Question
When there is a disaster of incident in the USA and they have a press conference

Why are there SO MANY people behind the one speaking
I mean - for these fires I can see why the Fire Chief and the local mayor
and may the governor or something
may be speaking and need to be there

but there always seems to be 20-30 other people just being there for no good reason

I presume it is so they can just be seen so they can say so for the next election

but why - don;t they have better things to be doing in the middle of a crisis??

Good point.
I have just watched an LA fire chief plus another official giving an update. There were 13 other people just standing behind them. They were a mix of people, most in casual clothes. I tried to work out why they were there but got no clue.

True but if it’s up to car driver eye level means the Lorry driver will have the same issue seeing cars and bikes and the road (which are in the fog) as anyone else

rarely has road works, or accidents!

we’ve had plenty of both this year

Just general Derps probably, look Ma ,I'm on the local wxcn News station, , ' do you know how the fire started?' why yes ma'am, Chris Rea farted......then the auberge field ignited it......then Whoosh.....everything is aflame

You will have to explain that to me.

I considered that you might 'tune' it for road use, therefore rendering it useless for driving down the A34

I was being sardonic, like having a bit of fun!

 

[Chris S]

The A34 is a notoriously bad road, I never liked using it.

You see what it's like when it gets to Birmingham. Stratford Rd in Sparkhill is gridlocked for most of the day.

been spending time every day visiting a hospital ward, in fact several hospital wards as they keep moving her about. And in each one there is what looks like a standard single 3 pin 240v electric socket, and on it, in big red letters "X-Ray" ?

didn't know they had portable x-ray machines (and how could they use them in a ward with 6 patients, and to my main question) why would it need to be on its own circuit ?

They do exist, and they do need a special circuit (although other things can also use that circuit, it isn't the case that the socket can only be used for x-ray machines, but that x-ray machines can only use the marked sockets).

system. (b) Designers should take note of the inherent high protective conductor (earth leakage) currents associated with a variety of electronic equipment. Examples of these are information technology equipment and mobile X-ray equipment, which can produce a higher allowable earth leakage current than normal medical electrical equipment.
And
For example, a typical X-ray generator uses a rectifier circuit to generate a d.c. intermediate voltage. Due to this, equipment manufacturers often advise the use of a Type B RCD.
