that the axes get closer to one another. 2. Prove that the "interval", defined as x² +v² + =² – c²¢ is a conserved quantity across reference frame transformations. 3. Consider two events. Give an example of coordinates x,y,z,t and x',y',z',t and relative

An asteroid of mass 1000 kg travels through space with speed a) What is the total energy of the asteroid? (You can leave your response as a math function, but please simplify as much as you can.) b) The asteroid has a rest length of 20 m. What length would an observer on Earth see? (You can leave your response as a math function, but please simplify as much as you can.)

Please please please answer as fast as possible please

A ball of mass m traveling at a speed of 0.80c has a perfectly inelastic collision with an identical ball at rest. If Newtonian physics were correct for these speeds, momentum conservation would tell us that a ball of mass 2m departs the collision with a speed of 0.40c. Let's do a relativistic collision analysis to determine the mass and speed of the ball after the collision. Part C What is the initial total energy? Give your answer as a fraction times mc². Don't forget that there are two balls. Express your answer in terms of c and m. IVD ΑΣΦ E= Submit Part D Uf = Request Answer Because energy can be transformed into mass, and vice versa, you cannot assume that the final mass is 2m. Instead, let the final state of the system be an unknown mass M traveling at the unknown speed uf. You have two conservation laws. Find uf. Express your answer in terms of c and m. Submit IVE ΑΣΦ ?

Suppose an alpha particle (which has a mass of 6.645 × 10-27 kg) is moving at 0.29c.Randomized Variablesv = 0.29 c   Part A) What is the momentum of the alpha particle in kg ⋅ m/s?

Events 1 and 2 are exploding firecrackers that each emit light pulses. In the reference frame of the detector, event 1 leaves a char mark at a distance 3.40 m from the detector, and event 2 leaves a similar mark at a distance 2.10 m from the detector. If the two events are simultaneous in the reference frame of the detector and occur at instant t = 0, at what instant of time will each light pulse be detected?

If an aircraft travels with a speed of 400 m/s in the air at 250 C, its Mach number will be: (Use Speed of sound in air at 00 C = 331 m/s and K = C+ 273)) %3D Select one: a. 1.16 b. 2.35 C. 6.9 -16, Critical Angle and Total Internal Reflection Jump to.. Practice Quil
