A 22.0-m-long bar of steel expands due to a temperature increase. A 11.0-m-long bar of copper also gets longer due to the same temperature rise. The two bars were originally separated by a gap of 1.6 cm. Assume the steel and copper bars are fixed on the ends, as shown in the following figure.
1)
Calculate the change in temperature if the gap is exactly "closed" by the expanding bars. (Express your answer to two significant figures.)
Answer in K
2)
Calculate the distances that the steel stretches. (Express your answer to two significant figures.)
Answer in mm
3)
Calculate the distances that the copper stretches. (Express your answer to two significant figures.)
Answer in mm

A) A stainless steel bar 11.8 cm long is welded end to end to a copper bar 22.6 cm long. Each bar has a square cross section, 2.0 cm on a side. The free end of the stainless steel bar is kept at 100∘C by placing it in contact with steam, and the free end of the copper bar is kept at with 0∘C by placing it in contact with ice. Both bars are perfectly insulated on their sides. What...

A 1.10-m-long metal bar is pulled to the right at a steady 4.0 m/s perpendicular to a uniform, 0.790-T magnetic field. The bar rides on parallel metal rails connected through R = 25.5-Ω, as shown in the figure (Figure 1), so the apparatus makes a complete circuit. You can ignore the resistance of the bar and the rails. A) Calculate the magnitude of the emf induced in the circuit. Express your answer using two significant figures. B)Find the direction of...
