b. \(6 \times 10^{-6}\) detik
c. \(3,29 \times 10^{-11}\) Coulomb
d. 0,01 mg

Jawab :
Soal Nomor 1a
\begin{aligned}
0,000000000723 \ meter &= \ .... nm \\
&=7,23 \times 10^{-10} \ m \times \frac{1 \ nm}{1\times 10^{-9} \ m} \\
&= 7,23 \times 10^{-10} \times (1 \times 10^{9}) \ nm\\
&= 7,23 \times 10^{-1} \ nm \\
&= 0,723 nm \\
\end{aligned}

Soal Nomor 1 b
\begin{aligned} 6 \times 10^{-6} \ detik &= \ ... \ nano \ detik \\ &= 6 \times 10^{-6} \ s \times \frac{1 \ ns}{1 \times 10^{-9}} \\ &= 6 \times 10^{-6} \times (1 \times 10^{9}) \ ns\\ &= 6 \times 10^{3} \ ns \\ &= 6.000 \ nano \ sekon \\ \end{aligned}     

Soal Nomor 1 c
\begin{aligned}
3,29 \times 10^{-11} \ C &= \ ... \ nC \\
&= 3,29 \times 10^{-11} \ C \times \frac{1 \ nC}{1 \times 10^{-9} \ C} \\
&= 3,29 \times 10^{-11} \times (1 \times 10^{9}) \ nC \\
&= 3,29 \times 10^{-2} \ nC \\
&= 0,0329 \ nC
\end{aligned}

Soal Nomor 1 d
\begin{aligned}
0,01 \ mg &= \ ... \ ng \\
&= 1 \times 10^{-2} mg \times \frac{1 \times 10{-3} \ g}{1 \ mg} \times \frac{1 \ ng}{1 \times 10^{-9}} \\
&= (1 \times 10^{-2}) \times (1 \times 10{-3}) \times (1 \times 10^{9}) \\
&= 1 \times 10^4 \ ng \\
&= 10.000 \ ng
\end{aligned}

Soal Nomor 2

Tuliskan nama awalannya!
a. \(120 \times 10^{-6}\) volt
b. \(27 \times 10^3\) gram
c. \(0,07 \times 10^{-9}\) meter
d. \(300 \times 10^{12}\) detik

Jawab :
Soal Nomor 2a
\begin{aligned}
120 \times 10^{-6} \ volt &= 120 \ \mu Volt
\end{aligned}

Soal Nomor 2b
\begin{aligned}
27 \times 10^3 \ gram \ = \ 27 \ kg
\end{aligned}

Soal Nomor 2c
