because E=Mc2 is rest energy. total energy also includes kinetic energy in the following relationship.
Et = sqrt( Er2 + Ek2 )
The measurement unit that describes the amount of energy food contains is the calorie. In nutrition, food energy is often expressed in kilocalories (kcal), where one kilocalorie equals 1,000 calories. This measurement indicates how much energy the body can obtain from consuming the food.
It relates the energy of a particle to it's mass. So, if you were to convert 1kg of material into pure energy, the energy you would get out would be calculated using E = mc2.However, this is just the simplified version for a particle that isn't moving. If the particle is moving with a momentum p, then the full formula is used: E2 = p2c2 + m2c4.
Heat, on a molecular or atomic level, is kinetic energy; fast moving particles are literally hotter. So, if a fast moving particle collides with a slower particle, there will be an exchange of energy. We know from basic physics that force equals mass times acceleration, so when a force is applied to a particle, that particle will accelerate. That is how heat is transferred particle by particle. All of this happens on such a small, sub-microscopic scale, that we do not see the mechanics of it, we just see heat being conducted.
The number of protons equals the number of electrons.
You can't.Mililiters is a volume measurement and milligrams is a mass measurement
You can not equate a measurement of volume (the ml) with a measurement of length (the cm).
No. - A gallon is a measurement of volume. - Centimetres are a measurement of length.
The watt is a unit of measurement as related to electrical energy. eg: one (1) kilowatt hour equals 3,412 BTUs.Another AnswerEnergy is not measured in watts, but in joules. A watt is used to measure power.
kilograms are a weight measurement cups are a measurement of volume.
When the length of the time is decreased more and more ,average velocity of the particles equals instantaneous velocity.
The period of a particle is the inverse of its frequency. Therefore, for a particle with a frequency of 315 Hz, the period can be calculated as 1/315 Hz, which equals 0.00317 seconds.
Einstein's famous equation E=mc^2, where E is energy, m is mass, and c is the speed of light, demonstrates the relationship between mass and energy. It implies that mass and energy are interchangeable and can be converted into each other. This equation is a cornerstone of modern physics and has been a key concept in the development of nuclear energy and particle physics.
