- दाब (P): प्रति एकक क्षेत्रफळाच्या बलाला दाब म्हणतात.
- दाबाचे एसआय एकक पास्कल (Pa) आहे.
दाब (P) = बल (F)/ क्षेत्रफळ (A)
- बल (F): पदार्थाची विश्रांतीची स्थिती किंवा गतीची स्थिती बदलणाऱ्या परस्परक्रियेला बल म्हणतात.
- बलाचे एसआय एकक न्यूटन (N) आहे.
बल (F) = वस्तुमान (m) × त्वरण (a)
- घनता (ρ): घनफळाच्या प्रति एकक वस्तुमानाला घनता म्हणतात.
- घनतेचे एसआय एकक किलोग्राम प्रति घनमीटर (किलो/मी3) आहे.
घनता (ρ) = वस्तुमान (m)/घनफळ (V).
स्पष्टीकरण
वस्तुमान/घनफळ = घनता.
म्हणून, पर्याय 3 योग्य आहे.
