Please help! this is due at 8:45 am! two cars are traveling down a road. the first car is traveling north at 55 mi/h, and the second is a few hundred yards south, traveling at 45 mi/h what is their relative velocity?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

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
