1. The Young's modulus for tin is 4.5x10^10. If the speed of sound in tin is measured to be 2.73km/s , find its density in (kg/m^3) . a)6.05x10^3 b)23.8x10^3 c)6.35x10^3 d)24.5x10^3 e)6.65x10^3 , E(tin)=4.5x10^10 ,speed of sound in tin=2.73km/s 2. v=sqrt(B/density) -where B is bulk modulus 3. if i substitute B as young's modulus I get answer a) in the choices. What is difference between bulk modulus and young's modulus and if there is what relation relates them.Thanks.
