1000 has one significant digit (only the 1 is interesting; you don't know anything for sure about the hundreds, tens, or units places; the zeroes may just be placeholders; they may have rounded something off to get this value)
Answer 2:
There is no way to know how many significant digits are in 1000. If you are forced to choose then there is 1 significant digit but, again, there is really no way to tell. If the count of significant digits is important, the number should be expressed in scientific notation.
