In a common but dangerous prank, a chair is pulled away as a person is moving downward to sit on it, causing the victim to land hard on the floor. suppose the victim falls by 0.40 m, the mass that moves downward is 63.0 kg, and the collision on the floor lasts 0.0830 s. what are the magnitudes of the (a) impulse and (b) average force acting on the victim from the floor during the collision?

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.
