To find the increase in the national debt over a 50-year period, we subtract the debt in 1971 from the debt in 2021.
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = $2.9617 \times 10^{13} - $3.98 \times 10^{11}
To subtract these values, we need to have them in the same scientific notation. In this case, we can convert $3.98 \times 10^{11}$ to $0.398 \times 10^{13}$.
Debt increase = $2.9617 \times 10^{13} - 0.398 \times 10^{13}$
Now, we can subtract the values:
Debt increase = $(2.9617 - 0.398) \times 10^{13}$
Simplifying the calculation:
Debt increase = $2.5637 \times 10^{13}$
Therefore, the national debt increased by $2.5637 \times 10^{13}$ during the 50-year period.
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = $2.9617 \times 10^{13} - $3.98 \times 10^{11}
To subtract these values, we need to have them in the same scientific notation. In this case, we can convert $3.98 \times 10^{11}$ to $0.398 \times 10^{13}$.
Debt increase = $2.9617 \times 10^{13} - 0.398 \times 10^{13}$
Now, we can subtract the values:
Debt increase = $(2.9617 - 0.398) \times 10^{13}$
Simplifying the calculation:
Debt increase = $2.5637 \times 10^{13}$
Therefore, the national debt increased by $2.5637 \times 10^{13}$ during the 50-year period.

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 = Debt in 2021 - Debt in 1971
Debt increase = $2.9617 \times 10^{13} - $3.98 \times 10^{11}
Calculating this:
Debt increase = $2.9617 \times 10^{13} - 0.398 \times 10^{13} = $2.5637 \times 10^{13}
Therefore, the correct answer is $2.5637 \times 10^{13}.
Debt increase = Debt in 2021 - Debt in 1971
Debt increase = $2.9617 \times 10^{13} - $3.98 \times 10^{11}
Calculating this:
Debt increase = $2.9617 \times 10^{13} - 0.398 \times 10^{13} = $2.5637 \times 10^{13}
Therefore, the correct answer is $2.5637 \times 10^{13}.

To find the difference between the sizes of the hydrogen and oxygen atoms, we subtract the size of the hydrogen atom from the size of the oxygen atom.
Difference = Size of oxygen atom - Size of hydrogen atom
Difference = 0.000000000152 m - 1.2 x 10^-10 m
Calculating this difference:
Difference = 0.000000000152 m - 0.00000000012 m = 0.000000000032 m
To express this difference in scientific notation, we write it as:
Difference = 3.2 x 10^-11 m
Therefore, the correct answer is 3.2 x 10^-11 m.
Difference = Size of oxygen atom - Size of hydrogen atom
Difference = 0.000000000152 m - 1.2 x 10^-10 m
Calculating this difference:
Difference = 0.000000000152 m - 0.00000000012 m = 0.000000000032 m
To express this difference in scientific notation, we write it as:
Difference = 3.2 x 10^-11 m
Therefore, the correct answer is 3.2 x 10^-11 m.

To determine which blood component has a bigger diameter and the approximate difference, we need to compare the diameters of a platelet and a red blood cell.
The diameter of a platelet is given as 2.33 x 10^-6 m.
The diameter of a red blood cell is given as 0.0000075 m.
To compare the diameters, we subtract the diameter of the platelet from the diameter of the red blood cell:
Difference = Diameter of red blood cell - Diameter of platelet
Difference = 0.0000075 m - 2.33 x 10^-6 m
Calculating the difference:
Difference = 0.0000075 m - 0.00000233 m = 0.00000517 m
To express the difference in scientific notation, we write it as:
Difference = 5.17 x 10^-6 m
Therefore, the correct answer is: A platelet has a bigger diameter than a red blood cell by 5.17 x 10^-6 m.
The diameter of a platelet is given as 2.33 x 10^-6 m.
The diameter of a red blood cell is given as 0.0000075 m.
To compare the diameters, we subtract the diameter of the platelet from the diameter of the red blood cell:
Difference = Diameter of red blood cell - Diameter of platelet
Difference = 0.0000075 m - 2.33 x 10^-6 m
Calculating the difference:
Difference = 0.0000075 m - 0.00000233 m = 0.00000517 m
To express the difference in scientific notation, we write it as:
Difference = 5.17 x 10^-6 m
Therefore, the correct answer is: A platelet has a bigger diameter than a red blood cell by 5.17 x 10^-6 m.

To find out how many more people live in China than in India, we subtract India's population from China's population.
Difference = China's population - India's population
Difference = 1.45 x 10^9 - 1,400,000,000
We need to convert the population of India from standard form to scientific notation:
Difference = 1.45 x 10^9 - 1.4 x 10^9
Calculating the difference:
Difference = 0.05 x 10^9 = 5 x 10^8
Therefore, the correct answer is: 5 x 10^8.
Difference = China's population - India's population
Difference = 1.45 x 10^9 - 1,400,000,000
We need to convert the population of India from standard form to scientific notation:
Difference = 1.45 x 10^9 - 1.4 x 10^9
Calculating the difference:
Difference = 0.05 x 10^9 = 5 x 10^8
Therefore, the correct answer is: 5 x 10^8.
