Acoaxial cable consists of alternating coaxial cylinders of conducting and insulating material. coaxial cabling is the primary type of non-fiber-optic cabling used for communications (i. e. cable tv) because of its superior ability to transmit electrical signal with minimum distortion. like all other kinds of cables, however, coaxial cables also have some self-inductance that has undesirable effects, such as producing some distortion and heating. consider a long coaxial cable made of two coaxial cylindrical conductors that carry equal currents i in opposite directions. the inner cylinder is a small solid conductor of radius a. the outer cylinder is a very thin walled conductor of radius b, electrically insulated from the inner conductor. the currents travel on the outer surface of each cylinder due to what is known as skin-effect. (a) describe the magnetic field in the region between and b. what is the functional form as a function of distance from the central axis, i. e. radius? you may use

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
