Platelets and red blood cells are components of the blood. A typical plate let and red blood cells have diameters of approximately 2.33x10^-6m and 0.0000075m, respectively. Which blood Component has a bigger diameter and appropriately by how much?

Answer 1

To determine which blood component has a bigger diameter, we compare the diameters of platelets and red blood cells.

The diameter of platelets is approximately 2.33x10^-6m.
The diameter of red blood cells is approximately 0.0000075m.

To compare the sizes, we can convert both to scientific notation and find the difference between the exponents.

2.33x10^-6 = 2.33 * 10^(-6)
0.0000075 = 7.5 * 10^(-6)

From the scientific notation, we can see that the exponent for both is -6. The difference lies in the coefficient, which is 2.33 for platelets and 7.5 for red blood cells.

To compare the coefficients, we subtract: 7.5 - 2.33 = 5.17

Therefore, red blood cells have a bigger diameter by approximately 5.17 times compared to platelets.
