Four wires with currents are arranged in the corners of a square. Current in the upper left corner (as viewed from your point of view) is 2I, all others are I. Direction of all currents is out of a page (towards you). The direction of net magnetic field in the center of a square is:
a. towards the upper right corner
b. towards the upper left corner
c. towards the lower right corner
d. towards the lower right corner
e. magnetic field is zero in the center

Which two objects have the greatest gravitational force acting between them

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
