A long, straight wire of radius R carries a steady current I thatis uniformly distributed through the cross section of the wire.

a). Using Ampere's Law, show the derivation of the equationfor the magnetic field in the region r > R.
b). And in the region r < R.

Ablock of mass 1.5 kg slides down an inclined plane that has an angle of 15. if the inclined plane has no friction and the block starts at a height of 3 m, how much kinetic energy does the block have when it reaches the bottom? acceleration due to gravity is g = 9.8 m/s2. a. 6.8 j b. 50.9 j c. 0 j d. 44.1 j
