Download Solution PDFसंकल्पना:
- मितीय सूत्र हे भौतिक राशीचे वस्तुमान, लांबी, वेळ आणि अँपियरच्या संदर्भात असलेली पदावली आहे.
स्पष्टीकरण:
- घनता: ही प्रति एकक आकारमानाचे वस्तुमान म्हणून परिभाषित केली जाते.
म्हणजेच, घनता = वस्तुमान/आकारमान
आता,
वस्तुमानाचे मितीय सूत्र = [M]
आकारमानाचे मितीय सूत्र = [L3]
घनता \(= \frac{{\left[ M \right]}}{{\left[ {{L^3}} \right]}}\)
∴ घनता = ML-3 T0
∴ घनतेचे मितीय सूत्र [ML-3 T0] आहे.
