- If general relativity offers the best description of what happens in the presence of gravity, why do physicists still make use of Newton’s equations in describing gravitational forces on Earth (when building a bridge, for example)?arrow_forwardRelativistic effects such as time dilation and length contraction are present for cars and airplanes. Why do these effects seem strange to us?arrow_forwardBecause you are moving with an enormous speed, your mission from the previous problem A.1will be influenced by the eects of time dilation described by special relativity: Your spaceshiplaunches in June 2020 and returns back to Earth directly a er arriving at Sirius.(a) How many years will have passed from your perspective?(b) At which Earth date (year and month) will you arrive back to Earth?www.arrow_forward
- The star Epsilon Eridani is 10.4 light-years from Earth. Imagine a spaceship that travels from Earth to Epsilon Eridani at a constant speed of 0.921c. On Earth, we would measure the time it takes for the ship to reach the star to be (10.4ly/0.921c)= 11.2 years. (a) How much time (in years) would it take the ship to travel from the Earth to the star as measured by a passenger aboard the ship? years (b) What is the distance to the star (in light years) as measured by a passenger aboard the ship?arrow_forwardWhat do you understand by time dilation? What is proper time and establish a relation for proper time. A beam of particle of half-life 2×10-8 sec travels in laboratory with speed 0.96 times the speed of light. How much distance does the beam travel before the flux falls to ½ time the initial flux.arrow_forwardAnswer both of the following questions regarding Special Relativity: a) An astronaut leaves their twin behind on Earth and departs on a journey on a spacecraft travelling at a speed of 0.840c. After 40.0 years pass on Earth, the astronaut returns to Earth to find that their age is now different from their twin. How old is the astronaut upon returning to Earth? b) A muon, travelling at a speed of 0.999c, travels a distance of 10.0 km from the Earth’s atmosphere to a muon detector on the surface of Earth (these distances are considered from Earth’s perspective). How far does the muon travel from its own perspective?arrow_forward
- Which of Einstein’s postulates of special relativity includes a concept that does not fit with the ideas of classical physics?Explain.arrow_forwardThe star 61 Cygni A is 11.4 light-years from Earth. Imagine a spaceship that travels from Earth to 61 Cygni A at a constant speed of 0.921c. On Earth, we would measure the time it takes for the ship to reach the star to be 11.4 ly 0.921c = 12.4 years. (a) How much time (in years) would it take the ship to travel from the Earth to the star as measured by a traveler aboard the ship? years (b) What is the distance to the star (in light years) as measured by a traveler aboard the ship? lyarrow_forwardRecall, from this chapter, that the factor gamma (γ) governs both time dilation and length contraction, where When you multiply the time in a moving frame by γ, you get the longer (dilated) time in your fixed fame. When you divide the length in a moving frame by γ, you get the shorter (contracted) length in your fixed frame. A passenger on an interplanetary express bus traveling at v = 0.99 takes a 5-minute catnap, according to her watch. Show that her catnap from the vantage point of a fixed planet lasts 35 minutes.arrow_forward

Explain why a moving clock appears to run slow?arrow_forward
