How much energy is contained in 0.525 g of matter? Recall the speed of light c = 3.00 * 10 ^ 8 * m / s = 1.86 * 10 ^ 5 * mi / s.

Particle A has a rest energy of 1192 MeV and is moving through the laboratory in the positive x direction with a speed of 0.450c. It decays into particle B (rest energy = 1116 MeV) and a photon; particle A disappears in the decay process. Particle B moves at a speed of 0.400c at an angle of 3.03° with the positive x axis. The photon moves in a direction at an angle with the positive x axis. A 0.45c What are the 0.40c photon Ө 3.03⁰ B in MeVs and your answer in three significant digits. in degrees of the photon? Give

A futuristic rocket ship of mass m,hip = 6.0 × 10° kg is sent into space carrying one person with the goal of traveling to nearby stars. The ship uses a newly discovered matter-antimatter drive that converts matter into energy at 100% efficiency. We will take Earth as the rest frame. For parts (a) through (d) you are interested in the portion of the spaceship's travel where it is using its drive to convert matter into the kinetic energy of the ship. (a) What is the speed of the ship when the work done by the ship's drive is equal to 150,000 TWh (the total energy used by humanity in 2014)? (b) How much work must the drive do for the rocket to reach a final speed of 0.95c? (c) How much matter would the drive need to annihilate in order for the ship to reach the final speed of 0.95c? Assume that the matter used in the antimatter drive is collected from the interstellar medium and that the mass of the ship remains constant. (d) When at the final speed of 0.95c, by what factor is the ship's…

The sun generates energy through nuclear fusion, which converts mass intoenergy. If the sun radiates 3.8 × 1026 W of power, calculate the rate at which the sun loses mass (i.e., kg/s). _________×109kg/s ?   Compare the energy produced per kg of fuel for the combustion of coal, d-d fusion and d-t fusion.d-d:  __________ ×107 MJ/kg?d-t:  ___________×108 MJ/kg  ?     The age of the sun has been estimated at 4.6 billion years. If it has radiatedenergy at the same rate throughout its lifetime, 3.8×1026 W and if its current mass is1.989×1030 kg, what fraction of its original mass has been lost _____________% ?

HINT (a) At what constant speed (in m/s) must a spacecraft travel on its journey to the star so that the Earth–star distance measured by an astronaut onboard the spacecraft is 4.36 ly?  m/s (b) What is the journey's travel time in years as measured by a person on Earth?   NO SCIENTIFIC NOTATION ANSWERS THANK YOU

A particle has a rest mass of 6.15 x 10-27 kg and a momentum of 4.24 x 10-18 kg-m/s. Determine the total relativistic energy E of the particle. J E = Find the ratio of the particle's relativistic kinetic energy K to its rest energy Erest- K Erest

10 L Special Relativity predicts that high-energy electrons increase in mass as they approach the speed of light. What kinetic energy will an electron have if it is travelling at 99.875% of the speed of light? Give your answer in MeV and in J. How many times greater is your result than the value the classical formula mv² gives? G AU
