Answer #1

Q2) Since the ruler can measure only 1mm, the actual uncertainty should be greater than or equal to 1mm.

so the correct uncertainity is 1mm and the correct rounded off value is 17.0cm

Q3)The correct uncertainty is 44.932km, and the correctly rounded off value is 6800.000km. Here, the uncertainty is the least distance the satelite can measure. and the last 2 place before the decimal points comes under this uncertain part. so we should round off till the 3rd place to the left of the decimal point.

Q4 is not readable.
