Question

1 Joule=107 erg prove that​

Answer 1

1joule =10000000erg

it's formula of joule when we change joule in erg

Answer 2

Explanation:

We know that,

1 Joule = 1 N m

1 N = 10^5 dyne

. ' . 1 dyne = 1/10^5 N ............... (i).

We prove, 1 Joule=10^7 erg.

Now,

1 erg = 1 dyne × 1 cm ( in C. G. S unit)

1 erg = 1/10^5 N × 1/100 m ( from eqⁿ (i) )

1 erg = 1/10^5 N × 1/10² m

1 erg = 1/10^7 N m

10^7 erg = 1 N m

10^7 erg = 1 Joule

That is proved :✔️✔️✔️✔️
