Una barra de estaño tiene la forma de un prisma recto de 4cm2 de base y 1m de longitud a la temperatura de 68º F. Determine la longitud y el volumen de esa barra a 518º F. Considere el coeficiente de dilatación lineal del estaño a = 20 x10-6ºC-1. me pueden ayudar con este ejercicio?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
