Question

what is the relation between joule and erg​

Answer 1

Explanation:

An erg is the amount of work done by a force of one dyne exerted for a distance of one centimeter. In the CGS base units, it is equal to one gram centimeter-squared per second-squared (g. cm2/s2). It is thus equal to 10−7 joules or 100 nanojoules (nJ) in SI units

Answer 2

Answer:

Explanation:

We know that 1J = 1N * 1M

                       1erg = 1dyne * 1cm

1 dyne = 10^5N

1 m = 10^2cm

So 1 joule = 10^5 * 10^2 = 10^7 erg
