In outer space, where there is no gravity or air resistance, an astronaut pushes on two moon rocks, using 12N of force on each. One rock has a mass of 2 kg, the other has a mass of 4 kg. Which statements are true? (Mark all true statements)
A. Both rocks will push back at the astronaut with 12 N.
B. Since the astronaut is weightless, he cannot push on the rocks.
C. Since both rocks are weightless, they do not push back on the astronaut.
D. The 4 kg rock pushes back on the astronaut twice as hard as the 2 kg rock.
E. Since both rocks are weightless, they will have the same acceleration.

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
