A long, straight wire lies along the x-axis and carries current I = 55.0 A in the +x-direction. A small particle with mass 3.00×10^−6kg and charge 8.00×10^−3C is traveling in the vicinity of the wire. At an instant when the particle is on the y-axis at y = 9.00 cm, its acceleration has components ax=−5.00×103m/s^2 and ay=+9.00×10^3m/s^2. At that instant what are the 2- and y-components of the velocity of the particle? Express your answer in kilometers per second. Enter your answers numerically separated by a comma.

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

Yvette hangs a 2.4kg bird feeder in the middle of a rope tied between two trees. the feeder creates a tension of 480 n in each side of the the rope.
