घनता:
- घनता म्हणजे सामग्री किती घट्ट बांधली जाते याचे मोजमाप आहे.
- हे प्रति एकक घनफळ वस्तुमान म्हणून परिभाषित केले आहे.
गणितीयदृष्ट्या, \(\rho =\frac{Mass}{Volume}\)
गणना:
दिलेल्याप्रमाणे:
लाकडाची परिमाणे = 6 सेमी × 8 सेमी × 5 सेमी, वजन = 1.92 N, g = 10 m/s2
वजन = वस्तुमान × गुरुत्वाकर्षण
⇒ 1.92 = वस्तुमान × 10
⇒ \(mass=\frac{1.92}{10}=0.192~kg\)
∵ घनता, ρ = \(\frac{Mass}{Volume}\)
⇒ ρ = \(\frac{0.192}{0.06~\times~0.08~\times~0.05}\)
⇒ ρ = 800 kg/m3
