Physics - Thoery of Relativity According to the twin paradox argument, a space traveller should age less than a stay-at-home friend. But relative to the space traveller, the stay-at-home friend made the journey and should therefore have aged less. The two perspectives seem symmetrical. What is wrong with this argument?

According to the twin paradox argument, a space traveller should age less than a stay-at-home
friend. But relative to the space traveller, the stay-at-home friend made the journey and should
therefore have aged less. The two perspectives seem symmetrical. What is wrong with this

- Nonea) Calculate the kinetic energy required to accelerate a single proton from a rest position to 0.9999c. The mass of a proton is 1.67x10*-27 kg. b) Find the ratio of the kinetic energy to the energy of a proton at rest. c) Explain why no particle accelerator will ever be able to accelerate any particle to the speed of light.1. A supertrain of proper length 195 m travels at a speed of 0.92c as it passes through a tunnel having proper length 90.0 m. How much longer is the tunnel than the train or vice versa as seen by an observer at rest with respect to the tunnel? meters
- Question 1 pleaseA particle traveling at 3.75 x 10^8 m/s is subjected to the special theory of relativity. How fast is this velocity in relation to the speed of light? * A.) it is 50% the speed of light B.) it is 75% the speed of light C.) it is 100% the speed of light D.) it is 125% the speed of light A particle traveling at 3 x 10^8 m/s is subjected to the special theory of relativity. How fast is this velocity in relation to the speed of light? * A.) it is 50% the speed of light B.) it is 75% the speed of light C.) it is 100% the speed of light D.) it is 125% the speed of lightThe speed of light relative to still water is 2.25 * 10^8 m/s. If the water is moving past us, the speed of light we measure depends on the speed of the water. Do these facts violate Einstein’s second postulate? Explain.
- 1) A 5-kg particle's momentum is (211, 329) kg*m/s. Calculate its kinetic energy. 2)Calculate the x-component of vSJ. vS = 6 km/s vJ = 9 km/s θ = 23o 3) In Jupiter's frame, the incoming spacecraft is moving rightward and upward, at 45o. The outgoing spacecraft, having already flown by, is going at the same relative speed, but leftward and upward, also at 45o. (See the figures.) You are going to transform back to the sun's frame and calculate the final outgoing speed. You need to follow several steps: Calculate the vector components of the outgoing vSJ. Add Jupiter's vector velocity to get the outgoing vS. Finally calculate the outgoing speed, vS = |vS| in km/s. Enter that as the final answer. use these parameters: vSJ = 4 km/s vJ = 8 km/sMultiple choice2. Suppose the boat A is moving relative to the water with a velocity of 6 m/s due east and boat B is moving with a velocity of 12 m/s due west. Assume that observers on both boats use reference frames in which the x direction points east. According to the Galilean veloc- ity transformation equations, what is the velocity of boat A relative to boat B. (Hint: Draw a picture. Be sure to define which object corresponds to which frame.)
- Can you answer question 2 part b?Part 1: Impossible Statements Which of the following statements are IMPOSSIBLE? Choose all that are. The rocket's speed was measured to be 0.15c. The rocket's rest length is 685 m. An observer flying by measured the rocket to be 185 m long. A rocket flying away from the Sun at 0.53c measured the speed of the photons (particles of light) emitted by the Sun to be c. An inertial reference frame had an acceleration of 3 m/s². The proper time interval between two events was measured to be 237 s. The time interval between the same two events (as measured by an observer not in the proper frame) was 167 s. Part 2: True Statements Which of the following statements are TRUE? Choose all that are. The Lorentz factor, y, has a range that extends from zero to infinity. The range for the velocity of an object extends from 0 m/s to the speed of light. The elapsed time between two events (as seen in any frame) can never be less than the proper time for those two events. An object's length (as seen in…5: Write down Lorentz transformation equations of special theory of relativity. Can a person, in principle, travel from Earth to the galactic center (which is about 23000ly distant) in 100 years? Try to calculate what is the constant speed it need to make the trip. Explain "mass is equivalent to energy".
