Explanation:

Your

answer is here i.e.=

10^8

Answer 2

The value is 10⁸erg/cm³.

Given : A physical quantity is found to be 10⁷J/m³.

To find : Its value in erg/cm³.

Solution :

We can simply solve this numerical problem by using the following mathematical process. (our goal is to calculate its value in erg/cm³)

Here, we need the following two mathematical relationships :

• 1 J = 10⁷ erg
• 1 m³ = 10⁶ cm³

So,

= 1J/m³

$= \frac{1J}{1 {m}^{3} }$

$= \frac{ {10}^{7} \: erg }{ {10}^{6} \: {cm}^{3} }$

= 10 erg/cm³

Now,

1 J/m³ = 10 erg/cm³

So,

10⁷ J/m³ = (10⁷ × 10) erg/cm³

or,

10⁷ J/m³ = 10⁸ erg/cm³

(This will be considered as the final result.)

Hence, the value is 10⁸erg/cm³.
