Question

How many significant figures does the number 520 have? What is the difference between a systematic error and a random error?

Answer 1

the number of sig. fig. really depends on the situation. if you are counting discrete objects, that are inseparable (i.e. you can't have half of a person), then i would say 520 has 3 sig. dig. but when you are considering it as a measurement obtained from an experiment, such as the distance traveled by a car, then it becomes arbitrary. unless 520 is followed by a decimal, which is "520.", then you say it has 3 sig. dig. the better way to do this is to write this in terms of scientific notation as 5.20X10^2. but generally, 520 has three sig. fig.

Answer 3

its has 2 significant figures
