Along cylindrical conductor carries current in one direction uniformly spread over the cross section. (i. e. j is directed parallel to the axis and is constant). a very thin layer of insulation surrounds the cylinder, which in turn is surrounded by a very thin cylindrical shell which shares its axis of symmetry with the inner cylinder. the current returns in the outer cylindrical shell. (a) find the energy stored in a length l of this composite cable. (b) find the self-inductance of this cable per unit length.

explanation:

a 2,000 calorie based diet.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
