A ray diagram is shown. A tree acts as the object further than 2 F away from a biconvex lens. The distance between 2 F and the o
bject is labeled W. The distance between F and 2 F is labeled X. There I a light ray parallel to the principal axis is bent through F on the image side of the lens. There is a ray straight through the center of the lens. The rays intersect a point below the principle axis between F and 2 F on the image side of the lens and is closer to the principal axis than the object is tall. The intersect point is labeled Z and the distance between F and 2 F on the image side of the lens is labeled Y. Which letter represents the location of the image produced by the lens? W X Y Z
If solid, cold metal like brass doesn't melt at room temperature like ice does, than the bass can stand much more heat then a ice cube, so it needs to be hotter to melt, so the melting point of ice is lower then brass's melting point
