Twin sisters Annie and Hannah are fighting
over their favourite toy. Annie pulls with a
force of 25N to the left. Hannah pulls with
a force of 30N to the right. What is the net
force on the toy?

Fnet = -25N + 30N = 5N
(25N is negative since left is negative)

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
