Astraight, nonconducting plastic wire 8.00 cm long carries a charge density of 100 nc/m distributed uniformly along its length. it is lying on a horizontal tabletop.
(a) find the magnitude and direction of the electric field that is produced 6.0cm directly above its midpoint.(b) if the wire is now bent into a circle lying flat on the table, find the magnitude and direction of the electric field on a point 6.0cm directly above its center.

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

The energy released by a nuclear fusion reaction is produced when

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.
