Answer :

Let's analyze and solve the problem step by step, based on the information provided in the table.

1. Understanding the Units and Conversion Factors:

- Row 1: [tex]\( 1 \, \text{m J} = 10 \, \text{प} \, \text{J} \)[/tex]
- Row 2: [tex]\( 1 \, \text{cJ} = 10 \, \square \, \text{J} \)[/tex]
- Row 3: [tex]\( 1 \, \square \, \text{J} = 10^{-9} \, \text{J} \)[/tex]
- Row 4: [tex]\( 1 \, \square \, \text{J} = 10^{-6} \, \text{J} \)[/tex]

2. Analyzing the Provided Data:

- Row 1 implies that millijoules (mJ) are being converted to some unit represented by प (possibly a localized unit) where [tex]\( 1 \, \text{mJ} \)[/tex] equals [tex]\( 10 \, \text{प} \, \text{J} \)[/tex].
- Row 2 implies that centijoules (cJ) are being converted to a unit represented by a placeholder [tex]\( \square \)[/tex], where [tex]\( 1 \, \text{cJ} \)[/tex] equals [tex]\( 10 \, \square \, \text{J} \)[/tex].

3. Identifying the Values Behind the Placeholder [tex]\( \square \)[/tex]:

- We need to resolve the placeholder [tex]\( \square \)[/tex] based on rows 3 and 4, which show:
[tex]\( 1 \, \square \, \text{J} = 10^{-9} \, \text{J} \)[/tex] and [tex]\( 1 \, \square \, \text{J} = 10^{-6} \, \text{J} \)[/tex].

Since the two rows (3 and 4) contradict each other by giving two different values for [tex]\( \square \, \text{J} \)[/tex], it suggests there might be an error or misunderstanding in the values provided for the conversion.

Based on all provided data, we conclude that the final answer cannot be definitively determined from the data given. The solution remains as:

None

This indicates an incomplete or inconsistent set of informations for final conclusion.
