Aforce, f1, of magnitude 2.0 n and directed due east is exerted on an object. a second force exerted on the object is f2 = 2.0 n, due north. what is the magnitude and direction of a third force, f3, which must be exerted on the object so that the resultant force is zero?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Determine the maximum r-value of the polar equation r =3+3 cos 0

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
