Why was niels bohr’s atomic model superior to all the earlier models? a. it proved that the atom was indivisible and therefore the smallest unit of matter. b. it showed how the electron could orbit the nucleus without falling into it. c. it was the first to show that the atom had no net charge. d. it used wave behavior to explain the positions of electrons around the nucleus.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
