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

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).

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea
