Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.107 N when their center-to-center separation is 60.0 cm. The spheres are then connected by a thin conducting wire. When the wire is removed, the spheres have a net positive charge and repel each other with an electrostatic force of 0.0310 N. What was the initial negative charge on one of the spheres, and what was the initial positive charge on the other

The law of entropy can also be called the law of increasing disorder, but this law seems to contradict the existence of living organisms that are able to organize chemicals into organic molecules. prepare for a class debate on the validity of the following arguments: a. living things are not subject to the laws of thermodynamics. b. the increase in the universe's entropy due to life processes is greater than the decrease in entropy within a living organism.
