Question

Calculate the velocity of longitudinal waves in aluminium bar. The density of
young's modulus of aluminium
2.8 x 10*3kg/m2 and 7 x 10"10
pascal
respectively.​

Answer 1

Answer:

5100 m/s

Explanation:

v=

ρ

Y

where, Y is the Young's modulus of steel bar and ρ is the

density of steel bar.

v=

7800

2×10
