There is a long straight wire carrying current i = 497 amperes. at a distance of 0.6 meter away, a small piece of wire (length 1 cm) carries a current of 12 amperes in a direction parallel to the long wire. (a) calculate the value of the b field generated by the long wire at the position of the small wire. b = t (b) using your result for b just found, calculate the force on the small wire. f = n

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

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.
