To find how much bigger Jupiter's radius is compared to Earth's, we need to find the difference between their radii.

Jupiter's radius = 4.3441 * 10^4 miles
Earth's radius = 3,959 miles

The difference between the radii can be found by subtracting Earth's radius from Jupiter's radius:

Jupiter's radius - Earth's radius = 4.3441 * 10^4 miles - 3,959 miles = 4.3441 * 10^4 miles - 0.3959 * 10^4 miles = 4.3441 * 10^4 miles - 0.3959 * 10^4 miles = 3.9482 * 10^4 miles.

Therefore, Jupiter's radius is approximately 3.9482 * 10^4 miles bigger than Earth's.

To subtract these two numbers, we need to ensure that they have the same exponent.

4.66×10^−5 - 7.34×10^−7

The exponents are already the same, so we can subtract the numbers:

4.66×10^−5 - 7.34×10^−7 = (4.66 - 0.0734) × 10^−5 = 4.5866 × 10^−5

Therefore, the result is 4.5866 × 10^−5.

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

2021 debt - 1971 debt = (2.9617 * 10^13) - (3.98 * 10^11)

To subtract the numbers, we need to ensure that they have the same exponent:

(2.9617 * 10^13) - (3.98 * 10^11) = (2.9617 * 10^13) - (0.398 * 10^13)

Now that the exponents are the same, we can subtract the numbers:

(2.9617 - 0.398) * 10^13 = 2.5637 * 10^13

Therefore, the U.S. national debt increased by 2.5637 * 10^13.

Apologies for the mistake. Let's redo the calculation:

2021 debt - 1971 debt = (2.9617 * 10^13) - (3.98 * 10^11)

To subtract the numbers, we need to ensure that they have the same exponent:

(2.9617 * 10^13) - (3.98 * 10^11) = (2.9617 * 10^13) - (0.398 * 10^13)

Now that the exponents are the same, we can subtract the numbers:

(2.9617 - 0.398) * 10^13 = 2.5637 * 10^13

Therefore, the U.S. national debt increased by $2.5637 × 10^13 in the 50-year period.

Apologies for the confusion. Let's redo the calculation:

Debt increase = 2021 debt - 1971 debt
Debt increase = (2.9617 × 10^13) - (3.98 × 10^11)

To subtract the numbers, we need to ensure that they have the same exponent:

Debt increase = (2.9617 × 10^13) - (3.98 × 10^11)
Debt increase = (2.9617 × 10^13) - (0.0398 × 10^13)

Now that the exponents are the same, we can subtract the numbers:

Debt increase = (2.9617 - 0.0398) × 10^13
Debt increase = 2.9219 × 10^13

Therefore, the U.S. national debt increased by $2.9219 × 10^13 in the 50-year period.

To find the difference between the sizes of these atoms, we need to subtract the size of the hydrogen atom from the size of the oxygen atom.

Size of oxygen atom - Size of hydrogen atom = (0.000000000152 m) - (1.2 × 10^-10 m)

To subtract the numbers, we need to ensure that they have the same exponent:

(0.000000000152 m) - (1.2 × 10^-10 m) = (1.52 × 10^-10 m) - (1.2 × 10^-10 m)

Now that the exponents are the same, we can subtract the numbers:

(1.52 - 1.2) × 10^-10 = 0.32 × 10^-10

However, we can simplify 0.32 × 10^-10 to express it in scientific notation. The exponent -10 can be left as is, and we move the decimal point to have a number between 1 and 10:

0.32 × 10^-10 = 3.2 × 10^-11

Therefore, the difference between the sizes of these atoms in scientific notation is 3.2 × 10^-11.

To determine which blood component has a bigger diameter, we need to compare the diameters of the platelet and the red blood cell.

Diameter of platelet = 2.33 × 10^-6 m
Diameter of red blood cell = 0.0000075 m

To compare the diameters, we can directly subtract the smaller one from the larger one:

Diameter of red blood cell - Diameter of platelet = (0.0000075 m) - (2.33 × 10^-6 m)

To subtract the numbers, we need to ensure that they have the same exponent:

(0.0000075 m) - (2.33 × 10^-6 m) = (7.5 × 10^-6 m) - (2.33 × 10^-6 m)

Now that the exponents are the same, we can subtract the numbers:

(7.5 - 2.33) × 10^-6 = 5.17 × 10^-6

Therefore, the red blood cell has a bigger diameter than the platelet, and the difference in diameter is approximately 5.17 × 10^-6 meters.

To find out how many more people live in China than in India, we need to subtract the population of India from the population of China.

Population of China - Population of India = (1.45 × 10^9) - (1,400,000,000)

To subtract the numbers, we need to ensure that they have the same units and scale:

(1.45 × 10^9) - (1,400,000,000) = (1.45 × 10^9) - (1.4 × 10^9)

Now that the exponents are the same, we can subtract the numbers:

(1.45 - 1.4) × 10^9 = 0.05 × 10^9

However, we can simplify 0.05 × 10^9 to express it without scientific notation:

0.05 × 10^9 = 50,000,000

Therefore, there are 50,000,000 more people living in China than in India.

(1.45 - 1.45) × 10^9 = 0 × 10^9

Therefore, there is no difference in population between China and India.

To find out how many more people live in China than in India, we need to subtract the population of India from the population of China.

Population of China - Population of India = 1.45×10^9 - 1,400,000,000

Since the population of India is already given in standard notation, we can subtract the numbers directly:

1.45×10^9 - 1,400,000,000 = 50,000,000

Therefore, there are 50,000,000 more people living in China than in India.

Population of China - Population of India = 1.45×10^9 - 1,400,000,000

1.45×10^9 can also be written as 1.45×10^9. Therefore, we can subtract the numbers directly:

1.45×10^9 - 1,400,000,000 = 50,000,000

So, there are 50,000,000 more people living in China than in India.

In scientific notation, this can be written as:

5×10^7

Therefore, the correct answer is 5×10^7.
