Which of the following numbers contains the designated CORRECT number of significant figures? Which of the following numbers contains the designated CORRECT number of significant figures? 156 000 3 significant figures 0.00302 2 significant figures 0.04300 5 significant figures 3.0650 4 significant figures 1.04 2 significant figures

156 000: 3 significant figures

Explanation:

The rules to identify the correct number of significant figures in a number are:

- All the non-zero digits are always significant

- Final (trailing) zeros are only significant if they are after the decimal point

- All zeros between non-zero digits are significant

Now we can apply these rules to the given numbers:

156 000: 3 significant figures --> TRUE. Only 1, 5 and 6 are significant figures here.

0.00302: 2 significant figures --> FALSE. Here the significant figures are only 3, 0 and 2, so there are 3 significant figures

0.04300: 5 significant figures --> FALSE. Here the significant figures are 4, 3, 0, 0: so, 4 sign. figures.

3.0650: 4 significant figures --> FALSE. Here there are 5 significant figures: 3,0,6,5,0

1.04: 2 significant figures --> FALSE. Here there are 3 significant figures: 1,0,4

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
