Which statement is false? multiple choice fission occurs among the heaviest isotopes, whereas fusion occurs more readily for light isotopes. the mass defect (δm) for a fission reaction is negative, whereas δm for fusion is positive. in order for fusion reactions to occur, temperatures must be in the millions of degrees. the fission of pu-239 atoms produces isotopes of many different elements. neutron-induced fission processes can occur at room temperature, rather than at millions of degrees.

Industrial processes often require the damping of vibrations. consider a workbench that uses four large ideal springs in place of traditional legs, with each spring supporting one corner of the workbench and exhibiting a force constant of 47500 n/m. this workbench is used when creating products that involve highly unstable chemicals. according to specifications, the acceleration of the manufacturing equipment must be held to less than 22.3 m/s2 for the manufacturing process to proceed safely. the amplitude of vibrations are expected to remain under 0.622 mm throughout. given that the workbench and maufacturing equipment combine to 6.05 kg, find the maximum acceleration expected of the equipment and workbench. (ignore the mass of the springs.)
