Answer:
Explanation:
=> the ratio of ths lengths of two rods is 4:3.
l₁/l₂ = 4/3
=> The ratio of their coefficients of cubical expansion is2:3.
∝₁/∝₂ = 2/3
=> The ratio of their linear expansion when they are heated through same temperature difference = ?
=> ∝ = Δl / l Δt
Δt = same
∝ = Δl / l
Δl = l*∝
=> Δl₁/ Δl₂ = l₁/l₂ * ∝₁/ ∝₂
= 4/3 * 2/3 = 8 / 9
४₁/४₂ = ∝₁/∝₂
