Along straight wire runs along the z-axis and carries a current of 24.0 a in the positive direction. another long straight wire runs along the line (x, y (15.0 cm, o). the magnetic fheld at points along the line (x. y) - (10.0 cm. o) has a magnitude of 32.0 microtesla and is directed in the +y-direction. what is the current in the wire at x - 15.0 cm? o a) 5.00 a in the +z-direction b) 4.00 a in the +z-direction c) 3.00 a in the 2 direction d) 1.00 a in the zdirection e) 6.00 a in the -z-direction

Apendulum has a mass of 1.5 kg and starts at a height of 0.4 m. if it is released from rest, how fast is it going when it reaches the lowest point of its path? acceleration due to gravity is g = 9.8 m/s2. a. 2.8 m/s b. 0 m/s c. 5.9 m/s d. 4.3 m/s

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
