- The speed of light in space is 3.00 x 108 m/s. The time for light from the Sun to reach Earth is 8 minutes 20 seconds. Therefore, the distance from the Sun to Earth is 2.40 x 109 m. 8.64 x 1012 m. 1.50 x 1011 m. 2.25 x 109 m.Someone in Earth's rest frame says that a spaceship's trip between two planets took 10.0 years, while an astronaut on the space ship says that the trip took 6.27 years. Find the speed of the spaceship (as measured by someone in Earth's rest frame) in terms of the speed of light. 0.959c 0.687c 0.489c 0.684c 0.779cThe Juno spacecraft arrived at Jupiter on July 4, 2016. Assuming the distance between the Earth and Jupiter is approximately 6.30 × 1011 m, determine the time, in minutes, for a signal traveling at the speed of light to reach Earth from Juno.
- A laser pointer is placed on a platform that rotates at a rate of 19 revolutions per minute. The beam hits a wall 8 m away, producing a dot of light that moves horizontally along the wall. Let 0 be the angle between the beam and the line through the searchlight perpendicular to the wall. How fast is this dot moving when 0 = Wall π ? 6 8 m Laser (Use decimal notation. Give your answer to one decimal place.) velocity of the dot: m/minRace rocket driver Suzy is heading down the final straightaway, approaching the finish line at 1.0 x 108 m/s. Her fans, at the finish line straight ahead, are shooting laser beams toward her (but not into her eyes). The speed of light is 3.0 x 108 m/s. How fast are the light waves approaching in Suzy's reference frame? 3. a) Light waves do not travel in Suzy's frame. b) 1.0 x 10² m/s c) 3.0 x 108 m/s d) 4.0 x 10² m/sDavid is 30 years old, and his sister Alexis is 25 years old, when David leaves to travel to planet Rosebud. Planet Rosebud is 20 lightyears away, and at rest relative to the Earth, and David travels at 0.85c. When David begins his journey, he is 5 years older than Alexis. When David arrives at planet Rosebud, who is older (David or Alexis) and by how much?
- Due to the Doppler effect, a moving aircraft sees the broadcast signals at 376 MHz from a stationary communications antenna that broadcasts signals at 354 MHz. Find the relative velocity between the aircraft and the broadcast station. Determine the direction of the moving aircraft.Consider the case of two kids, Sam and Peter, riding a train and playing catch in an empty car. The train is moving to the right at 10 m/s. The kids can throw the ball at a speed of 5 m/s. The side of the car is transparent and a poodle named Max can see the boys playing inside. What is the speed and direction of Sam’s throw to Peter, according to Max? Explain.How long should it take the voices of astronauts on the Moon to reach the Earth? Assume that the only significant time is the transit time from the Earth to the Moon, at the speed of light. Suppose that the astronaut on the surface of the Moon, the receiver on the surface of the Earth, and the centers of the Earth and the Moon are aligned. The distance between the centers of the Earth and the Moon is 384×103km, the radius of the Earth is 6.38×103km, the radius of the Moon is 1.74×103km.
- Clark Kent (a.k.a. Superman) is standing in the doorway of the entrance to a 525-meter-long hallway. (Lc = 525 m) Suddenly, Barry Allen (a.k.a. The Flash) runs down the length of the hallway at high speed (only 28% of the speed of light), as measured by Clark. (p or vc% = 28%) (Remember: c = 0.3 m/ns)Interactive LearningWare 28.10 reviews the concepts that play roles in this problem. The distance from earth to the center of our galaxy is about 30,000 ly (1 ly = 1 light year = 9.47 × 1015 m), as measured by an earth-based observer. A spaceship is to make this journey at a speed of 0.9990c. According to a clock on board the spaceship, how long will it take to make the trip? Express your answer in years. (1 yr is equal to 3.16 × 107 s.)The starship Enterprise approaches the Klingon home world with speed 0.6c relative to the planet. To announce its arrival, the Enterprise sends a message in a projectile that travels toward the planet with speed 0.4c relative to the Enterprise. At what speed does Klingon at the surface of the planet see the projectile approach? Using relativistic velocity equation.
