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, we can compare the given diameters of the platelet and the red blood cell.
The diameter of a platelet is given as 2.33×10^−6 m.
The diameter of a red blood cell is given as 0.0000075 m.
To compare the two diameters, we can convert them to standard decimal notation.
2.33×10^−6 m = 0.00000233 m
Comparing the two values, we see that the diameter of the red blood cell (0.0000075 m) is larger than the diameter of the platelet (0.00000233 m).
To determine the difference in diameter, we subtract the diameter of the platelet from the diameter of the red blood cell:
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 determine which blood component has a bigger diameter, we need to compare the diameters of platelets and red blood cells.
The diameter of a typical platelet is approximately 2.33×10^−6 m.
The diameter of a typical red blood cell is approximately 0.0000075 m.
To compare the sizes, we can subtract the diameter of the platelet from the diameter of the red blood cell.
0.0000075 m - 2.33×10^−6 m = 0.00000517 m
The red blood cell has a larger diameter by approximately 0.00000517 m.
To determine which blood component has a bigger diameter and by how much, we need to compare the diameters of the platelet and the red blood cell.
Given:
Diameter of a platelet = 2.33×10^−6 m
Diameter of a red blood cell = 0.0000075 m
To make a fair comparison, we can convert both values to scientific notation:
Diameter of a platelet = 2.33×10^−6 m
Diameter of a red blood cell = 7.5x10^−6 m
Comparing the exponents of the powers of 10, we see that the platelet has a smaller exponent (-6) than the red blood cell (-6). This means that the platelet is smaller in size.
To find the difference in diameters, we subtract the diameter of the platelet from the diameter of the red blood cell:
Difference in diameters = Diameter of the red blood cell - Diameter of the platelet
= (7.5x10^−6 m) - (2.33×10^−6 m)
= 5.17×10^−6 m
Therefore, the red blood cell has a bigger diameter than the platelet by approximately 5.17×10^−6 meters.
