A box having a weight of 8 lb is attached to a massless rod with length 2 feet. The initial speed of the box is 5 ft/s. Neglect friction and size of the box. If a moment of 10 ft-lb causes the box to increase its velocity from 5 ft/s to 10 ft/s, determine: rictly no di without written permissTON. a) The time it takes for the box to go from 5 ft/s to 10 ft/s b) The total work done during the time that the box goes from 5 ft/s to 10 ft/s c) The tension in the rod when the box has reached 10 ft/s

Asmall, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely responds when it is released? it will move toward the large ball because like charges repel. it will move toward the large ball because like charges attract. it will move away from the large ball because like charges repel. it will move away from the large ball because like charges attract.

Eddy whose mass is 55kg climbs up the 1.50 meter high stairs in 2s. calculate eddy’s power rating

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
