Um fio de latão tem 50m de comprimento a 20°C. Determine o seu comprimento se ele for aquecido até a temperatura de 60 °C. Considere o coeficiente de dilatação linear médio do latão igual a 18.10-6 °C -1

Idont understand the question

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.

Ihope you find the answer

  concave means having an outline or surface that curves inward like the interior of a circle or sphere. so the mirror curves inward.
