[tex]a = \frac{3 \times 1.2}{150} \times \frac{ {10}^{2} \times {10}^{ - 5} }{ {10}^{2} } = 0.024 \times \frac{ {10}^{ - 3} }{ {10}^{2} } = 0.024 \times {10}^{ - 5} = 2.4 \times {10}^{ - 7} [/tex]
[tex]b = \frac{50 \times 0.3}{25} \times \frac{ {10}^{2} \times {10 }^{ - 6} }{ {10 }^{ - 5} } = 0.06 \times \frac{ {10 }^{ - 4} }{ {10}^{- 5} } = 0.06 \times {10}^{ - 1} = 6 \times {10}^{ - 3} [/tex]
