Consider the two points B(2,4) and C(-1,-5) in the xy-plane. The coordinates are given in meters. A 20-N force is applied at point B at 120 degrees counterclockwise from the positive direction of the x-axis (where positive direction is horizontal to the right). Note that the force vector is also in the xy-plane (2D case). What is the magnitude of the moment of this force about point C?

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
