Question

One joule is numerically equal to*

(a) 10⁵ erg

(b) 10⁹ erg

(c) 10⁷ erg

(d) 10¹²erg

​

Answer 1

Answer:

c

Explanation:

c is the answer of this question

Answer 2

Answer:

(c) 10⁷erg

Explanation:

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