... (c) (5 points) You have two rods of the same length and diameter, but they are made of different materials. The rods will be used to conect two regions of different temperature such that energy will transfer through the rods by heat. They can be connected in series or in parallel as shown in the fi ...

... You have seen how a changing magnetic field can induce a “swirling” current in a conductor (the beginning of this lecture). If a conductor and a magnetic field are in relative motion, the magnetic force on charged particles in the conductor causes circulating currents. These currents are called “edd ...

... When electrons hit the target in an X-ray tube, only a small percentage of their energy is converted into X-rays. What happens to the rest of their energy and how does this influence the type of target used? converted to heat target material must have (very) high melting point / (specific example, e ...
