hey, thank god you had commented this, btw, my professor used E=mc2 to calculate the velocity of a moving electron instead of the general expression m2c2=E2/c2−p2, so is he wrong here? Third line (I mean, I think he is wrong, but he is my tutor, so, I sought your...
How much kinetic energy does the mass have? What speed of the kinetic energy of a particle will equal its rest energy? At what speed does the kinetic energy of particle equal its rest energy? How to calculate KE when it has double the mass? What is the kinetic energy of a 5 kg ball...
An object has a mass of 8.99 KG and is moving at 2.55 m/s. How much kinetic energy does it have? What is the magnitude of the momentum of a 0.0033-kg marble whose speed is 0.55 m/s? Calculate the momentum of an object if: ...
Question: A particle of mass m(0) travels at a speed 0.21c. At what speed will its momentum be doubled? Motion of Relativistic Particles: Let's consider a particle moving in space. When the speed of this particle is at a rate at which it's a substantial fr...
Matter has inherent energy so it can vibrate or orbit “forever” in an atom, which can be released as in E=mc2 but I don’t see how matter and energy can be different forms of the same thing. What we call matter on any large scale is just huge collections of these atomic particles...
The allegory of the cave must be analyzed in the total context of the Republic. Plato, having established that a "Philosopher King" needed to rule the Republic, finds himself in a bit "dilemma," i.e. how do I find a "Philosopher King" from among the people who are unfit as leaders....
At what speed does the kinetic energy of particle equal its rest energy? A particle of mass m has a kinetic energy of 2mc^2 , What are its total energy E and magnitude of momentum p? 1. E = 3mc2 , p = 2...
