You hang a heavy ball with a mass of 40 kg from a silver rod 2.8 m long by 2.2 mm by 2.7 mm. You measure the stretch of the rod, and find that the rod stretched 0.002384 m. Using these experimental data, what value of Young's modulus do you get? Y = 7.75e11 J× N/m2 The atomic mass of silver is 108 g/mole, and the density of silver is 10.5 g/cm³. Using this information along with the measured value of Young's modulus, calculate the speed of sound in silver.

Question
You hang a heavy ball with a mass of 40 kg from a silver rod 2.8 m long by 2.2 mm by 2.7 mm. You measure the stretch of the rod, and find that the rod stretched 0.002384 m.
Using these experimental data, what value of Young's modulus do you get?
Y = 7.75e11
X N/m2
The atomic mass of silver is 108 g/mole, and the density of silver is 10.5 g/cm3.
Using this information along with the measured value of Young's modulus, calculate the speed of sound in silver.
