letter B. this is to prepare the scientist, the possible outcome of their
research before the experimental design whether they are wrong or not.
Answer:
The answer is A sorry if i'm wrong
Explanation:
Isotopes refer to different atoms of the same element (i.e. same number of protons) that differ in the number of neutrons they have (giving them different atomic weights). Atomic weight is the sum of protons and neutrons (each contributes 1 atomic mass unit).
Carbon has 6 protons by definition. If you have a carbon-13 atom (the 13 referring to its mass), the atom has 13 - 6 = 7 neutrons. Since it's neutral, protons = electrons, so there are also 6 electrons.
Sulfur has 16 protons by definition. If you have a sulfur-32 atom, the atom has 32 - 16 = 16 neutrons. Since it's neutral, protons = electrons, so there are also 16 electrons.
Answer:
it will not change
Explanation:
if the forces are of equal force then there would be no movement because one force was not stronger to move it
