A lapidary plate at rest is turned on to cut a gemstone. The plate rotates until it reaches a tangential speed of 12.0 m/s. What is the centripetal acceleration of a point 0.10 m from the center of the plate? 1.2 m/s2
14.4 m/s2
1440 m/s2
120 m/s2

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.

Iwould have to say sorry i can't elaborate more. hope this though!

How are period and frequency related to each other? dperiod is the reciprocal of frequency.

Mass and velocity are the 2 factors used to calculate kinetic energy. the equation for kinetic energy is (1/2)mv^2. hope this !
