To convert the dimensions from meters to millimeters, we need to multiply by 1,000 (since 1 meter is equal to 1,000 millimeters).
The width of the sticky note is given as 1.25 × 10^(-8) meters. Multiplying by 1,000 gives:
1.25 × 10^(-8) × 1,000 = 1.25 × 10^(-5) millimeters.
The length of the sticky note is given as 2.5 × 10^(-6) meters. Multiplying by 1,000 gives:
2.5 × 10^(-6) × 1,000 = 2.5 × 10^(-3) millimeters.
Therefore, the dimensions of the sticky note in millimeters are 1.25 × 10^(-5) millimeters wide by 2.5 × 10^(-3) millimeters long.
So the correct answer is: 1.25×10−5 by 2.5×10−3 millimeters.
To convert the dimensions from meters to millimeters, we need to multiply each dimension by 1,000, because 1 meter is equal to 1,000 millimeters.
Given that the dimensions are 1.25×10^(-8) meters wide and 2.5×10^(-6) meters long, we can convert them to millimeters as follows:
1.25×10^(-8) meters wide × 1,000 millimeters/meter = 1.25×10^(-8) × 1,000 millimeters
= 1.25×10^(-8 + 3) millimeters
= 1.25×10^(-5) millimeters wide
2.5×10^(-6) meters long × 1,000 millimeters/meter = 2.5×10^(-6) × 1,000 millimeters
= 2.5×10^(-6 + 3) millimeters
= 2.5×10^(-3) millimeters long
Therefore, the dimensions of the sticky note in millimeters are 1.25×10^(-5) by 2.5×10^(-3) millimeters.
