घनत्व:
- घनत्व इस बात का माप है कि सामग्री कितनी दृढ़ता से एक साथ पैक की जाती है।
- इसे द्रव्यमान प्रति इकाई आयतन के रूप में परिभाषित किया गया है।
गणितीय रूप से,, \(\rho =\frac{Mass}{Volume}\)
गणना:
दिया गया:
लकड़ी के आयाम= 6 cm × 8 cm × 5 cm, = 1.92 N, g = 10 m/s2
भार = द्रव्यमान × गुरुत्व
⇒ 1.92 = mass × 10
⇒ \(mass=\frac{1.92}{10}=0.192~kg\)
∵ घनत्व, ρ = \(\frac{Mass}{Volume}\)
⇒ ρ = \(\frac{0.192}{0.06~\times~0.08~\times~0.05}\)
⇒ ρ = 800 kg/m3
