Platelets and red blood cells are components of the blood. A typical platelet and red blood cell have diameters of approximately 2.33x10^-6m and 0.0000075m, respectively. Which blood component has a bigger diameter, and approximately by how much?
To determine which blood component has a bigger diameter, we can compare the diameters of platelets and red blood cells.
The diameter of a platelet is approximately 2.33x10^-6m, and the diameter of a red blood cell is approximately 0.0000075m.
To make a direct comparison, we can express both measurements in scientific notation with the same exponent:
Platelet diameter: 2.33x10^-6m
Red blood cell diameter: 7.5x10^-6m
Comparing the two expressions, we can see that the red blood cell has a bigger diameter. The difference in diameter can be calculated by subtracting the platelet diameter from the red blood cell diameter:
7.5x10^-6m - 2.33x10^-6m = 5.17x10^-6m
Therefore, the red blood cell has a bigger diameter than the platelet, approximately by 5.17x10^-6m.
To determine which blood component, platelets or red blood cells, has a bigger diameter and by approximately how much, we need to compare the given diameters of each component.
The given diameter of a platelet is approximately 2.33 × 10^-6 m.
The given diameter of a red blood cell is approximately 0.0000075 m.
To make a fair comparison, we need to convert the diameter of the red blood cell from scientific notation to standard decimal notation. This can be done by moving the decimal point 7 places to the right, resulting in the diameter of the red blood cell being approximately 0.0000075 m.
Comparing the two diameters, we can clearly see that the diameter of a red blood cell (approximately 0.0000075 m) is significantly larger than the diameter of a platelet (approximately 2.33 × 10^-6 m).
To find the difference between the diameters, we can subtract the diameter of the platelet from the diameter of the red blood cell.
Approximately:
diameter of red blood cell - diameter of platelet
= 0.0000075 m - 2.33 × 10^-6 m
This gives us approximately 0.00000516 m as the difference in diameter between the red blood cell and the platelet.
To determine which blood component has a bigger diameter and by approximately how much, we can directly compare the diameters of the platelet and red blood cell.
The diameter of a platelet is given as approximately 2.33x10^-6 m.
The diameter of a red blood cell is given as approximately 0.0000075 m.
To make a comparison, we can convert both values to scientific notation for easier comparison, since they are already in scientific notation.
The diameter of a platelet in scientific notation is 2.33x10^-6 m.
The diameter of a red blood cell in scientific notation is 7.5x10^-6 m.
Now, comparing the values, we can see that the diameter of a red blood cell (7.5x10^-6 m) is larger than the diameter of a platelet (2.33x10^-6 m) by 5.17x10^-6 m.
Therefore, the red blood cell has a bigger diameter than the platelet, by approximately 5.17x10^-6 m.
