What is a planetary nebula?Group of answer choicesthe expanding shell of gas that is left when a white dwarf explodes as a supernovathe cloud of gas and dust from which protostars formthe expanding shell of gas that is blown off by a star when it becomes a white dwarfa disk of gas surrounding a protostar that may form

Question 3Which of the following is NOT required for the formation of a large nearly isotropic Oort cloud full of many small bodies, assuming the scenario that we discussed is the dominant mechanism? 1 pointA planet like Jupiter which is massive enough to scatter bodies out of the solar systemPassing stars which perturb the orbits of low perihelion, high semimajor axis objectsA smaller planet like Neptune to scatter icy bodies inward so they can be ejected by a more massive planet like JupiterA population of small bodies which is close enough to a planet to get scattered outwardMultiple stellar encounters to randomize the cometary orbits into an isotropic cloudAll of these are required
