From the doc: perldoc -f split
As a special case, specifying a PATTERN of space (' ') will
split on white space just as "split" with no arguments does.
Thus, "split(' ')" can be used to emulate awk's default ...
So, /' '/ in your regex causes a pattern match on a
literal ' '. When the search fails, the entire $string is
returned:

No, there's no split on a newline. You'd have to specify
/\n/ for that to happen. In your case, the whole string
is returned since the pattern match fails. This would've
been clear if your code had been:
foreach my $value {...@value) { print "=$value=\n"; }
which would've printed:
=108 ambulance 100

No, single quotes don't impact the split but only
whether interpolation occurs inside the string.
