52 c in a p(w J)?

I'm sorry, but the phrase "52 c in a p(w J)" is not a standard unit of measurement or a commonly used phrase. It's impossible to give you a meaningful answer without knowing what you're trying to describe.

Could you please clarify what you mean by "52 c in a p(w J)?" Perhaps you're asking:

* About a specific calculation? Provide more context, like what the variables represent (e.g., "c" is for Celsius and "J" is for Joules).

* About a specific scientific concept? Tell me what you're trying to learn about.

I'm here to help, but I need more information to understand your question!
