Everyday Science / Physics — Multiple-choice practice
ایلومینیم میں آواز کی رفتار _____ ہے؟
- A. 5620 m/s
- B. 7220 m/s
- C. 4820 m/s
- D. 6420 m/s
Correct answer
6420 m/s
Explanation
Explanation The speed of sound in aluminium is approximately 6420 meters per second . It is significantly faster than the speed of sound in air due to aluminium's higher density and elastic properties. The speed of sound in different materials: Air: 332 m/s Sea water: 1530 m/s Lead: 2160 m/s Gold: 3240 m/s Brick: 3650 m/s Copper: 4760 m/s Glass: 5100 m/s Aluminium: 6420 m/s
