Answer:
2x10⁸ erg
Explanation:
We can rewrite 20 J as 20 kg·m²/s². In order to convert into CGS, we would need to convert it into g·cm²/s².
We can do that with a series of conversion factors, in which the units that we want to convert from are canceled and only the units we want to convert to remain:
- 20 kg·m²/s² * [tex]\frac{1000g}{1kg} *(\frac{100cm}{1m})^2[/tex] = 2x10⁸ g·cm²/s²
Another way of writing 2x10⁸ g·cm²/s² is as 2x10⁸ erg.
