The size of a hydrogen atom is about 1.2×10^−10 m across. The size of an oxygen atom is 0.000000000152 m across. What is the difference between the sizes of these atoms in scientific notation?(1 point)

To find how much the debt increased in the 50-year period, we need to subtract the debt in 1971 from the debt in 2021.

Debt increase = $2.9617×10^13 - $3.98×10^11

First, let's convert both numbers into scientific notation:
Debt increase = $29.617×10^12 - $0.398×10^12

Next, we can subtract the two numbers:
Debt increase = $29.617×10^12 - $0.398×10^12
Debt increase = $29.219×10^12

Therefore, the debt increased by $29.219×10^12, or $29.219 trillion, in the 50-year period.

To find the difference between the sizes of the hydrogen and oxygen atoms in scientific notation, we need to subtract the size of the hydrogen atom from the size of the oxygen atom.

Difference = Size of oxygen atom - Size of hydrogen atom

In scientific notation:
Difference = (0.000000000152 m) - (1.2×10^−10 m)

Next, we convert both numbers into scientific notation:
Difference = 1.52×10^-10 m - 1.2×10^-10 m

Now we can subtract the two numbers:
Difference = 1.52×10^-10 m - 1.2×10^-10 m
Difference = 0.32×10^-10 m

Finally, we can simplify the result:
Difference = 0.32×10^-10 m = 3.2×10^-11 m

Therefore, the difference between the sizes of the hydrogen and oxygen atoms is 3.2×10^-11 m in scientific notation.
