Verified step by step guidance1
Step 1: Understand the units involved. 'pm' stands for picometers, which is a unit of length in the metric system equal to 10^-12 meters. 'cm' stands for centimeters, which is equal to 10^-2 meters.
Step 2: Convert 155 pm to centimeters. Since 1 pm = 10^-12 meters, first convert picometers to meters: 155 pm = 155 x 10^-12 meters.
Step 3: Convert meters to centimeters. Since 1 meter = 100 centimeters, multiply the result from Step 2 by 100 to convert meters to centimeters.
Step 4: Compare the two quantities. Now that both quantities are in centimeters, compare the numerical values to determine which is smaller.
Step 5: Conclude which quantity is smaller based on the comparison from Step 4.
