The water is going to have a lower freeze point but when the air temperature get down to 32 degrees you have to have the system circulating. Once you get to the single digits all bets are off as far as freeze damage. The salt generator will only make chlorine if the water temperature is above 50 degrees. My recommendation is when it gets that cold winterize the pool it is highly unlikely you will be using it and you will have peace of mind that your equipment will be protected.
The full VIN, no, but they have to have the last eight digits placed on the outside of the vehicle.
It depends on the two digits entered. Anything from 00 to 29 is taken as being the years 2000 to 2029. Anything from 30 to 99 is taken as being as being 1930 to 1999. You need to enter 4 digits if the year is outside of these ranges.It depends on the two digits entered. Anything from 00 to 29 is taken as being the years 2000 to 2029.

Because - 'absolute zero' (0 Kelvin or -373 Celsius) - is the temperature at which everything freezes. Scientific testing has not found any substance or object that does not freeze below absolute zero.
It depends. There are usually 9 or 10 significant digits after the "0" trunk code. All mobile phones have 10 significant digits following the "0" trunk code. Dialing from outside the UK, the "0" trunk code is replaced with the country code, "44".

The area code for London is 020, or +44 20 from outside the UK.

I have revised this answer. This question is harder than it looks!The numbers 69, 6009 or 98886, for example, would have rotational symmetry (looks the same when rotated by 180 degrees) but not reflection symmetry.So I think the answer is going to be something like:A number which consists of the digits 6 and 9 plus or minus the digits 0 & 8 AND has the digits in the necessary order to maintain rotational symmetry.
It depends where you are calling from:If you are making the call to a land-line from within Giza or Cairo (i.e. a local call), it's 8 digits; e.g. 12345678If you're calling a land-line from outside Giza or Cairo (e.g. Alexandria), you prefix the number with 02; e.g. 02-12345678 (10 digits)If you're calling a land-line from outside Egypt, you prefix the number with +202; e.g. +20-2-12345678If you're calling a cell number from outside Egypt, you prefix the number with +20; e.g. +20-10-123-4567
A quadrillion has 16 digits.
There is no such thing as scientific digits. There are 6 digits in the number of which 3 are SIGNIFICANT (not scientific) digits.
