Nuclear gamma ray the nucleus dysprosium-160 (containing 160 nucleons) acts like a spinning object with quantized angular momentum, l2 = l(l + 1)ℏ2, and for this nucleus it turns out that l must be an even integer (0, 2, 4...). when a dy-160 nucleus drops from the l = 2 state to the l = 0 state, it emits an 87 kev photon (87 ✕ 103 ev). (a) what is the moment of inertia of the dy-160 nucleus?

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
