Answer:
It appears that the solution you have provided is not a direct answer to the question "What is e=?". However, the statement you provided is a well-known concept in physics, where Einstein's famous equation E=mc² suggests that energy (E) and mass (m) are equivalent and interchangeable, and that they are two different manifestations of the same thing. The constant "c" in the equation represents the speed of light in a vacuum. This concept has had profound implications in the field of physics and has been used to develop nuclear energy and nuclear weapons.
Explanation:
Here's a step-by-step explanation of Einstein's famous equation, E=mc²:
The equation E=mc² stands for "energy equals mass times the speed of light squared".
In physics, "energy" refers to the ability of a system to do work, and it is measured in joules (J).
"Mass" refers to the amount of matter in an object and is usually measured in kilograms (kg).
"c" represents the speed of light in a vacuum, which is approximately 299,792,458 meters per second (m/s).
The equation shows that energy and mass are equivalent and interchangeable. In other words, mass can be converted into energy, and energy can be converted into mass.
The conversion factor between mass and energy is the speed of light squared, which is an enormous number. This means that even a small amount of mass can produce a significant amount of energy when it is converted.
The equation has been used to explain a variety of phenomena, such as the energy released in nuclear reactions and the behavior of particles at high speeds.
It has also led to the development of nuclear energy and nuclear weapons, which rely on the conversion of mass into energy.
Overall, E=mc² is a fundamental equation in physics that has had a profound impact on our understanding of the universe and our ability to harness its energy.
