Questions about Agency Law, Partnerships, and Corporations occur.

Can you help explain these by stating the issue, rule, how to apply it, and what conclusion can be drawn for each one?  Thanks.

1.  Dick Driver carelessly smashes his car into the rear end of another car while driving on a busy street.   Although Dick had no way of knowing this, the other car's truck was filled with dynamite.  The collision causes the dynamite to explode.  The explosion miraculously misses Dick, but it causes the shattering of a window on the third floor of a nearby office building. The falling glass cuts Pete Pedestrian, who was walking on the street below. Pete files suit against Dick.  



2.  As a prank, Joe signs Susan's name to a pro-abortion petition that appears in a local newspaper.  Susan is passionately opposed to abortion.  Thus, Susan sues Joe for both defamation and false light.  



3.  Foremost company is a national company that installs computers for major corporations.  In all of its contracts, there is a release clause or waiver that states that Foremost is not liable for damages caused by the negligent installation of the computers.  Bob buys a computer from Foremost, read the contract and release clause and signed it.  Later, Bob sues Foremost for negligent installation.
