? An aluminum rod is 20 cm long and a steel rod is 80 cm long when both rods are at a temperature of 15°C. Both rods have the same diameter. The rods are joined end-to-end to form a rod 100 cm long. The coefficients of linear expansion of aluminum and steel are \(2.4 \times 10^{-5} \, \text{K}^{-1}\) and \(1.2 \times 10^{-5} \, \text{K}^{-1}\), respectively. The temperature is raised to 85°C. The increase in the length of the joined rod, in mm, is closest to:- 0.81- 1.0- 1.2- 1.4- 0.60Options are provided for the user to select the correct answer. **Graph/Diagram Description:**There are no graphs or diagrams in this image.

The expression to solve for the increase in the length of the rod is as follows: ΔL=LαTf-Ti…

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
