A 2.00 kg mass hangs at rest 1.50 meters above the floor. The hanging mass is attached to a spool by a massless string that runs over a frictionless pulley. The string is wrapped around a spool with a radius of 0.12 meters. The mass is released causing the spool to spin. The moment of inertia of the spool is 0.72 kgm^2. Required:
What is the linear velocity of the mass just before it hits the floor and what is the angular velocity of the spool at that moment?

What is a carrier wave and how does it affect what you hear on the radio

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
