Answer:
7.93 × 10⁻¹³ km/s
Explanation:
Step 1: Given data
Rate of growth of the fingernails (r): 2.50 cm/year
Step 2: Convert "r" from cm/year to km/year
We will use the following conversion factors.
- 1 m = 100 cm
- 1 km = 1000 m
Step 3: Convert "r" from km/year to km/s
We will use the following conversion factors.
- 1 year = 365 day
- 1 day = 24 h
- 1 h = 60 min
- 1 min = 60 s
2.50 cm/year is equal to 7.93 × 10⁻¹³ kilometers/second.
