Auniform square crate is released from rest with corner d directly above a and it rotates about a until its corner b impacts the floor and then it rotates about b. the floor is rough enough to prevent slipping and the corner at b does not rebound on impact. determine, (a) as a function of g and `, the angular velocity of the crate ! e2 just before impact. (b) as a function of ! e2, the angular velocity of the crate immediately after impact ! e3. (c) the fraction of energy lost during the impact. (d) the maximum achieved after the impact. during the impact, assume that the weight force is non-impulsive.

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

The amount of potential energy possessed by an elevated object is equal to what?

An electron in an x-ray machine is accelerated through a potential difference of 1.00 × 104 v before it hits the target. what is the kinetic energy of the electron in electron volts?
