platelet and red blood cells are components of the blood. A typical platelet and red blood cell have diameters of approximately 2.33\times 10^(-6)m and 0.0000075m, respectively. Which blood component has a bigger diameter, and approximately by how much? (1 point)
To compare the diameters of platelets and red blood cells, we need to calculate the difference between the two values.
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 find the difference, we subtract the diameter of the platelet from the diameter of the red blood cell:
0.0000075 m - 2.33 x 10^(-6) m
Converting the values to scientific notation, we have:
7.5 x 10^(-6) m - 2.33 x 10^(-6) m
Combining like terms, we get:
5.17 x 10^(-6) m
Therefore, the difference in diameter between a red blood cell and a platelet is approximately 5.17 x 10^(-6) meters.
To find out which blood component has a bigger diameter and approximately by how much, we can compare the given diameters of the platelet and red blood cell.
The diameter of the platelet is given as 2.33 × 10^(-6) m, which is equivalent to 0.00000233 m.
The diameter of the red blood cell is given as 0.0000075 m.
Now, let's compare the two diameters:
0.0000075 m - 0.00000233 m ≈ 0.00000517 m.
Therefore, the red blood cell has a bigger diameter than the platelet by approximately 0.00000517 m.
To find out which blood component has a bigger diameter, we can compare the given diameters of the platelet and the red blood cell.
The diameter of a platelet is given as approximately 2.33 × 10^(-6) m.
The diameter of a red blood cell is given as approximately 0.0000075 m.
To compare these two values, we can convert them to scientific notation with the same exponent.
2.33 × 10^(-6) m is equivalent to 2.33 × 10^(-6) × 10^9 nm (1 meter is equal to 10^9 nanometers), which simplifies to 2.33 × 10^3 nm.
0.0000075 m is equivalent to 0.0000075 × 10^9 nm, which simplifies to 7.5 × 10^3 nm.
Comparing the values, we can see that 7.5 × 10^3 nm is larger than 2.33 × 10^3 nm.
Therefore, the red blood cell has a bigger diameter than the platelet, and it is bigger by approximately 7.5 × 10^3 nm - 2.33 × 10^3 nm = 5.17 × 10^3 nm.
So, the red blood cell is bigger than the platelet by approximately 5.17 × 10^3 nm.
