Answer is Right!
Answer is Wrong!
The correct answer is $\boxed{\text{C}}$. 1 joule is equal to $10^6$ ergs.
An erg is a unit of energy in the CGS system of units. It is equal to the work done by a force of one dyne acting through a distance of one centimeter. The joule is a unit of energy in the International System of Units (SI). It is equal to the work done by a force of one newton acting through a distance of one meter.
The conversion factor between ergs and joules is $1\text{ J} = 10^7\text{ ergs}$. This means that there are $10^6$ ergs in 1 joule.
