Question 1

In 1 second:

1 sec = x × 2 μsec
1 × 10^6 μsec = x × 2 × 10-6μsec
<math>x = \frac{10^6}{2} = 5 \times 10^{5} = 500,000</math>

In 1 minute:

500,000 * 60 = 30,000,000

Question 2

1cm = 1 \times 10-2m 1Gm = 1 \times 109m

<math>\frac{10^9}{10^{-2}} = 10^{11}\frac{cm}{Gm}</math>

Question 3

  • Kilo-ohm
  • Megajoule
  • microfarad
  • millihenry
  • picoamp
  • Gigavolt
