Answer:

Explanation:

When collecting samples, avoid small areas where the soil conditions are obviously different from those in the rest of the field—for example, wet spots, old manure and urine spots, places where wood piles have been burned, severely eroded areas, old building sites, fencerows, spoil banks, and burn-row areas.

This stadium can hold 100,000, or 1x10, people. The
Mekhanik [1.2K]

Answer:

1 x 10^13 stadiums will be needed in this scenario

Explanation:

We are told that

1 stadium holds = 1 × 10^5 people and

Number of iron atoms = 1 × 10^18 atoms

If the stadium carries an equivalent number of atoms as that of people.

We can infer that 1 stadium will carry 1 × 10^5 atoms.

The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.

Number of stadiums = Total number of atoms ÷ Number of atoms per stadium

= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium

= 1 × 10^13 Stadiums

This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums
