Explaining Magnetic Domains
Taylor places a nail on a bar magnet. The nail sticks to
the magnet when lifted up off the table. She touches a
paperclip to the nail and it sticks to the nail. Explain what
happened to the magnetic domains of the nail before and
after touching it to the bar magnet.

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.
