Answer:
b 2 only
Explanation:
The mass of an electron is 9.10938356 × 10⁻³¹ kilograms while the mass of a proton is 1.6726219 × 10⁻²⁷ kilograms. It can be seen that a proton is heavier than an electron.
Atoms do not always have the same number of neutrons and protons. For, example ¹³C has 6 protons and 7 neutrons.
Atoms do have most of the mass concentrated at the center called the nucleus. The nucleus has protons and neutrons. As protons have positive charge and neutrons have no charge the nucleus has a positive charge.
The answer would be he will spin slower. The bean bag is not spinning beforehand it
contacts the experimenter, so (through conservation of rotational momentum) he
must stock the rotational momentum mandatory to make it spin at the same degree
as his lap. Consequently, he ends up spinning slower.
"a black hole forms when any object reaches a certain critical density, and its gravity causes it to collapse to an almost infinitely small pinpoint."
I know its not straight forward with the answer
