A train emits a normal frequency ( f) of 300 Hz. What shifted frequency ( fs) will you hear if the train moves at 35.0 m/s AWAY from you? The following information is given to you: Speed of sound = 343 m/s. fs = f x [v / (v - vs) ］ fs = f x [v / (v + vs) ］

An inclined plane wrapped around a metal shaft is a a. lever b. screw c. pulley d. wedge

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
