In the n-3 level and for a given orbital angular momentum, one of the two angles closest to 90 that the total angular momentum makes with the z-axis is 75°. to what value of m, must this direction correspond, and what it the value of j, the total angular momentun quantum number? if the orbital angular momentum is making the smallest possible angle with the z-axis, write the spectroscopic notation for this state.

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

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter
