Question

Which of the following is NOT equal to 50 millimeters?

1) 5,000,000 nanometers
2) 50,000 micrometers
3) 5 centimeters
4) 0.05 meters

Answer 1

The option that is NOT equal to 50 millimeters is 5,000,000 nanometers, because 5,000,000 nanometers is equivalent to only 5 millimeters.OPTION A.

Step-by-step explanation:

Among the options given, the value that is NOT equal to 50 millimeters is 5,000,000 nanometers (nm). To understand why, we need to consider the metric conversions between these units of length:

• 1 nanometer (nm) = 10-9 meters
• 1 micrometer (μm) = 10-6 meters
• 1 millimeter (mm) = 0.001 meters
• 1 centimeter (cm) = 0.01 meters
• 1 meter (m) = 1,000 millimeters

Using these conversions:

• 5,000,000 nm = 5 mm (because 1,000,000,000 nm = 1 m)
• 50,000 μm = 50 mm (because 1,000 μm = 1 mm)
• 5 cm = 50 mm (because 1 cm = 10 mm)
• 0.05 m = 50 mm (because 1 m = 1,000 mm)

Therefore, the correct answer is that 5,000,000 nanometers (option 1) is not equal to 50 millimeters; it is actually equivalent to 5 millimeters.
