Question
Express each number in scientific notation.(a) $0.000000001 \mathrm{~s}$ (time it takes light to travel $1 \mathrm{ft}$ )(b) $0.143 \mathrm{~s}$ (time it takes light to travel around the world)(c) $0.000000000001 \mathrm{~s}$ (time it takes a chemical bond to undergo one vibration)(d) $0.000001 \mathrm{~m}$ (approximate size of a dust particle)
Step 1
000000001$ in scientific notation, we need to move the decimal point 9 places to the right. So, we get $1 \times 10^{-9}$. Show more…
