Question

Which of the following has zeros that are not significant?

2.05 m/s

10.0 J

1.30 N

100 kg

Answer 1

Answer: Either 10.0 J or 1.30 N

10.0 J

1.30 N

All zero's preceding the first integers are never significant. For example: 0.0078 has two significant figures. All zero's after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures

Answer:

100 kg

Explanation:

With the absence of a decimal point, only the 1 would be significant.
