To find the difference between the sizes of these atoms in scientific notation, we need to subtract the size of the hydrogen atom from the size of the oxygen atom.
Size of hydrogen atom: 1.2 × 10^(-10) m
Size of oxygen atom: 1.52 × 10^(-10) m
Now let's subtract the sizes:
1.52 × 10^(-10) m - 1.2 × 10^(-10) m = 0.32 × 10^(-10) m
Since 0.32 is between 0.1 and 1, we can rewrite it as 3.2 × 10^(-11), moving the decimal point one place to the left.
Therefore, the difference between the sizes of these atoms is 3.2 × 10^(-11) m.
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?

Platelets and red blood cells are components of the blood. A typical platelet and red blood cell have diameters of approximately 2.33×10^−6 m and 0.0000075 m, respectively. Which blood component has a bigger diameter, and approximately by how much?
To determine which blood component has a bigger diameter and by approximately how much, we need to compare the diameters of the platelet and red blood cell.
Diameter of platelet: 2.33 × 10^(-6) m
Diameter of red blood cell: 0.0000075 m
Let's compare the diameters:
2.33 × 10^(-6) m is equivalent to 2.33 × 10^(-6) m.
Since 0.0000075 is larger than 2.33 × 10^(-6), the red blood cell has a bigger diameter.
To calculate how much bigger it is, we can subtract the diameter of the platelet from the diameter of the red blood cell:
0.0000075 m - 2.33 × 10^(-6) m = 0.0000075 m - 0.00000233 m = 0.00000517 m
Therefore, the red blood cell has a diameter that is approximately 0.00000517 m bigger than the platelet.

Diameter of red blood cell: 0.0000075 m
Let's compare the diameters:
2.33 × 10^(-6) m is equivalent to 2.33 × 10^(-6) m.
Since 0.0000075 is larger than 2.33 × 10^(-6), the red blood cell has a bigger diameter.
To calculate how much bigger it is, we can subtract the diameter of the platelet from the diameter of the red blood cell:
0.0000075 m - 2.33 × 10^(-6) m = 0.0000075 m - 0.00000233 m = 0.00000517 m
Therefore, the red blood cell has a diameter that is approximately 0.00000517 m bigger than the platelet.

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.
China's population: 1.45 × 10^9
India's population: 1,400,000,000
To begin, let's convert India's population to scientific notation: 1,400,000,000 = 1.4 × 10^9
Now let's subtract the populations:
China's population - India's population = 1.45 × 10^9 - 1.4 × 10^9 = 0.05 × 10^9
Since 0.05 is between 0.1 and 1, we can rewrite it as 5 × 10^7, moving the decimal point one place to the left.
Therefore, there are 5 × 10^7 (or 50,000,000) more people living in China than in India.
