could use some help with these 10pts best answer! Two examples of radioactive minerals are calcite and dolomite. feldspar and quartz. bornite and azurite. carnotite and uraninite. Metals form positive ions because they easily gain electrons. become neutral. lose electrons. decay. The composition of Earth‘s inner core is solid iron and nickel. solid iron only. solid nickel only. none of the above. A Foucault pendulum provides evidence of Earth‘s rotation. axial tilt. parallax. revolution. A Foucault pendulum provides evidence of Earth‘s rotation. axial tilt. parallax. revolution.
carnotite and uraninite. because of uranium lose electrons. none of the above. inner core is very hot therefore metals must be melting. and will reach its liquid phase rotation. most reasonable answer. rotation.
standard car: 2 axles. just look at how many sets of 2 wheels there are. there are 2 sets of 2 on a car, so there are 2 axles. if you want to get really technical, there could be 3: one in the rear and two in the front. but the two would be the two arms coming off the transaxle. but it really just counts as one.
2 axles. A front wheel drive car uses two seperate axles from the transaxle, but for toll booth purposes, you pay toll for two axles. - Stuart

1) Uraninite has uranium, so wouldn't you expect it to be radioactive? Carnotite and Uraninite. 2) Atoms consist of protons, neutrons, and electrons. Electrons have a negative charge. So, what would make an atom become a positive ion? Losing electrons. 3) This is in your textbook, as well as all over the interwebs. 4) Same. You can figure these out, I promise.
