Technically, every particle attracts every other particle. The Shell theorem says that for spherical objects of uniform density, where neither object is inside the other, we can regard them as though all the mass of each object were located at the center of mass of that object.
The Shell Theorem may apply to forces besides gravity, (notably the Coulomb Force) but it would be the center of charge, rather than the center of gravity.
Calcium Carbonate is a type of rock mineral.
Answer:
i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.
I Believe A is correct is correct because atoms are basically the building blocks of all type of matter, without atoms, there is no matter
B is correct as well because the amount protons of in an atom do define the element. E.g. There is 8 protons in an oxygen atom. oxygen is the 8th element on the periodic table.
C is incorrect because the atomic number is always different
D is incorrect as we already determined that Protons define the element
So A and B should be your answers
Answer:
''The relationship between air pressure, air density, or altitude? As altitude increases, pressure increases. As altitude increases, air density increases. Air pressure and density are lowest at sea level.''
