Answer» Hii Dear SIS!❤️ Your Answer: 250.471cm² Explanation: PROBLEM Given: A copper plate has an AREA of 250cm^2 at 0°C. Calculate the area of this plate at 60°C. Given [coefficient of linear expansion of copper is alpha l=1.7×10^-5°C^-1. Solution: Given : =>Copper plate area=A₀=250cm² [I am assuming linear expansion of copper as :1.7x 10⁻⁵ C⁻¹ ] =>Here, is the method :β=2α=2x1.7x 10⁻⁵ C⁻¹ =>3.4x10⁻⁵ C⁻¹ ΔT=>(60-0)=60° Aθ=>A₀(1+βΔT) A₆₀=>50(1+3.14x10⁻⁵ x60)=250(1+0.001884)=250.471cm² Area of copper plate at 60 degree=250.471cm² ^_^ Hope My Answer Helps You!
