since the force of gravity on the moon is smaller

in significant figures, which zeros are NOT considered significant?

A. zeros before a digit, but after a decimal
B. zeros between two non-zero numbers
C. zeros in a whole number before a stated decimal
D. zeros in a whole number before an implied decimal

I think its A

Answer 43

or B

Answer 44

either A or D I think

Answer 45

hmm which one should we choose then?

Answer 46

something like 0.000000501 has 3 sig figs (5, 0, 1) because the zeros in front aren't counted

Answer 47

something like 7,000,000 has only 1 sig fig

Answer 48

but if you said 7,000,000.0, then it would have 7 sig figs

Answer 49

so then we should pick A right?

Answer 50

D could be lumped together with C somehow, not sure though

Answer 51

so I would think D is partially true, which means we can eliminate it

Answer 52

so yeah, A

Answer 57

what do you think I got C for my answer now

Answer 58

I would think that a law is absolute, but a theory can be challenged

Answer 59

if it couldn't be challenged, then it would be perfect and there wouldn't be any flaws

Answer 60

oh alright, so then B would be a reliable answer?
