Which quantity can be calculated using the equation E = mc2?the energy needed to split an atom into separate protons, neutrons, and electrons
the energy needed to split the nucleus into separate protons and neutrons
the energy needed to remove an electron from an atom
the energy needed to add an electron to an atom
Answers
Answer;
-The energy needed to split an atom into separate protons, neutrons, and electrons
Explanation;
E = mc² The equation is derived directly from Einstein’s Special Theory of Relativity .
Each of the letters of E = mc2 stands for a particular physical quantity. Writing them out in full we get:
Energy = mass × the speed of light squared
In other words: E = energy (measured in joules, J), m = mass (measured in kilograms, kg), c = the speed of light (measured in metres per second, ms-1), but this needs to be squared.
Explanation :
Einstein's equation is given by :
..............(1)
m is the mass
c is the speed of light
The energy needed to split an atom into separate protons, neutrons, and electrons can be calculated by using equation (1).
The energy needed to split the nucleus into separate protons and neutrons is called nuclear binding energy.
The energy needed to remove an electron from an atom is called ionization energy.
The energy needed to add an electron to an atom is called electron affinity.
So, the correct option is (A).

Final answer:
Aristotle supported geocentrism, the view that the Sun and all the planets revolve around the Earth. He did not support the concept of free-fall speed being independent of weight, a concept later verified by Galileo. Aristotle also proposed the existence of a fifth element, ether, in heavenly bodies.
Explanation:
Aristotle, the ancient Greek philosopher, supported the view that the Sun and all the planets revolve around the Earth. This model is known as Geocentrism or Ptolemaic system. His belief was widely accepted until the Copernican revolution in the 16th century, which provided a heliocentric model. The heliocentric model, the belief that the Earth and other planets revolve around the Sun, was questioned by Aristotle.
Furthermore, Aristotle did not support the view that the speed of a free-falling object is independent of its weight. This idea was later verified by Galileo. Also, the idea of every action having an equal and opposite reaction is associated with Newton's third law of motion, a concept that emerged much later than Aristotle's time. Lastly, Aristotle did propose the existence of a fifth element, ether, that he believed existed in the heavenly bodies. Hence, he did not support the view that ether does not exist in heavenly bodies.

In fact the idea Aristotle had was that this explained something about the nature of the universe. He noticed that when you push an object, it slows down and stops. Therefore he divided the universe into 'earth-like stuff' which preferred to remain stationary, and 'heavenly stuff' which preferred to be in motion. Newton showed this idea to be false when he effectively unified motion and being at rest - if you move at a constant velocity (like in a very large ship) you can't tell if you're moving at a constant velocity or whether you are at rest
