Answer :

Final answer:

The number of significant figures in each measurement is as follows: 143 kg (3), 8.75 x 10 -2 g (3), 0.074 m (2), 1.072 cm (4), 0.05730 m (4), 8765 L (4), 11 soccer players (2), and 40.007 m (5).

Explanation:

The number of significant figures in each measurement are as follows:

  1. 143 kg: 3 significant figures.
  2. 8.75 x 10 -2 g: 3 significant figures.
  3. 0.074 m: 2 significant figures. (Leading zeros are not counted as significant figures)
  4. 1.072 cm: 4 significant figures.
  5. 0.05730 m: 4 significant figures. (Here, zero at the end is counted as it is after the decimal)
  6. 8765 L: 4 significant figures.
  7. 11 soccer players: 2 significant figures.
  8. 40.007 m: 5 significant figures.

In the context of scientific measurements, significant figures represent the precision of a value. Leading zeros never count as significant figures, but trailing zeros (zeros at the end of a number) do count if they are after the decimal.
