To solve the problem we will simply perform equivalence between both expressions. We will proceed to place your units and develop your internal operations in case there is any. From there we will compare and look at its consistency
At the same time we have that
Therefore there is not have same units and both are not consistent and the correct answer is B.
Answer:
1.82°C
Explanation:
presumir inicial comprimento = l₀ = 5 m
dado que:
coeficiente de expansão (α) = 22 x 10⁻⁶, A variação no comprimento (ΔL) = 0.0002 m,
inicial comprimento = l₀ = 5 m
variação na temperatura = ΔT
para Calcular a variação na temperatura, nós usamos a fórmula:
substituindo valores:
variação na temperatura = 1.82°C
