Which of the following is not equal to 50 millimeters?
a) 5,000,000 nanometers b) 0.05 meters c) 5 centimeters d) 50,000 micrometers
Solution:
To answer this question we need to convert al the values to a common unit using the metric system
50 millimeters = 50 × 10-3 meters = 5 × 10-2 m (since, 1mm = 10-3 m)
5,000,000 nanometers = 5 × 106 × 10-9 = 5 × 10-3 m (since, 1nm = 10-9 m)
0.05 meters = 5 × 10-2 m
5 centimeters = 5 × 10-2 m (since, 1cm = 10-2 m)
50,000 micrometers = 5 × 104 × 10-6 = 5 × 10-2 m (since, 1μm= 10-6 m)
Hence, 5,000,000 nanometers is not equal to 50 millimeters
Which of the following is not equal to 50 millimeters?
Summary:
Option a) - 5,000,000 nanometers is not equal to 50 millimeters
