Question

A lab technician is driving a cell that has a diameter 4.32 X10^-4 millimeters. Each of the new cells has a diameter measuring exactly one half of the diameter of the original cell. Which is the diameter of a new cell?

Answer 1

The diameter of the original cell is 4.32 x 10⁻⁴ mm.

The new cell has 1/2 the diameter of the original cell.
The new diameter is 0.5*(4.32 x 10⁻⁴ mm) = 2.16 x 10⁻⁴ mm

Answer: 2.16 x 10⁻⁴ millimeters
