After an unfortunate accident occurred at a local warehouse, you were contracted to determine the cause. A jib crane collapsed and injured a worker. The horizontal steel beam had a mass of 85.10 kg per meter of length, and the tension in the cable was =12040 N. The crane was rated for a maximum load of 500 kg. If =5.000 m, =0.450 m, =2.000 m, and ℎ=2.250 m, what was the magnitude of L (the load on the crane) before the collapse? The acceleration due to gravity is =9.810 m/s2.

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
