1. An observer sees two events apart at aseparation of 800 m. How fast must a secondobserver be moving relative to the first to seethe two events occur simultaneously?2. Suppose you stay home on Earth while yourtwin sister takes a trip to a distant star andback in a spaceship that travels at 99% of thespeed of light. If both of you are 25 years oldwhen she leaves and you are 45 years oldwhen she returns, how old is your sister whenshe gets back?This is the question! i dont have the time ofoccurance between the two eventscould you do the seconnd instead?

As directed the second question will be answered. This question is based on Twin Paradox Twin A will…

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".
