Question
The length of a rod is $(10.15 \pm 0.06) \mathrm{cm}$ what is the length of two such rods?(a) $(20.30 \pm 0.06) \mathrm{cm}$(b) $(20.30 \pm 1.6) \mathrm{cm}$(c) $(10.30 \pm 0.12) \mathrm{cm}$(d) $(20.30 \pm 0.12) \mathrm{cm}$
Step 1
15 \pm 0.06) \mathrm{cm}$. This means the rod's length can be anywhere from $10.15 - 0.06 = 10.09 \mathrm{cm}$ to $10.15 + 0.06 = 10.21 \mathrm{cm}$. Show more…
