Question

A particle of rest mass ₀ moves with a speed of 0.9. Calculate its relativistic mass and momentum.

Answer 1

Answer:

Figure 1. The National Spherical Torus Experiment (NSTX) has a fusion reactor in which hydrogen isotopes undergo fusion to produce helium. In this process, a relatively small mass of fuel is converted into a large amount of energy. (credit: Princeton Plasma Physics Laboratory)

A tokamak is a form of experimental fusion reactor, which can change mass to energy. Accomplishing this requires an understanding of relativistic energy. Nuclear reactors are proof of the conservation of relativistic energy.

Conservation of energy is one of the most important laws in physics. Not only does energy have many important forms, but each form can be converted to any other. We know that classically the total amount of energy in a system remains constant. Relativistically, energy is still conserved, provided its definition is altered to include the possibility of mass changing to energy, as in the reactions that occur within a nuclear reactor. Relativistic energy is intentionally defined so that it will be conserved in all inertial frames, just as is

Answer 2

Using the formula, relative mass=m0/whole root 1-v^2/c^2 ,u can find your answer where v is the speed and c is the speed of light in vacuum and m0 is the rest mass. Hope you get it. All the best.
