(b) How many meters is it to Andromeda, the nearest large galaxy, given that it is 2.54 × 106 ly away? (c) The most distant galaxy yet discovered is 13.4 × 109 ly away. How far is this in meters?

Suppose the primed and laboratory observers want to measure the length of a rod that rests on the ground horizontally in the space between the helicopter and the tower (Fig. 39.8B). To derive the length transformation L = L (Eq. 39.5), we had to assume that the positions of the two ends were determined simultaneously. What happens to the length transformation equation if both observers measure the end below the helicopter at one time t1 and the other end at a later time t2?
Two astronomical events are observed to occur at a time of 0.30 s apart and a distance separation of 2.0109m from each other. How fast must a spacecraft travel from the site of one event toward the other to make the events occur at the same time when measured in the frame of reference of the spacecraft?
(a) How long in seconds does it take a radio signal to travel 180 km from a transmitter to a receiving antenna? (b) We see a full Moon by reflected sunlight. How much earlier did the light that enters our eye leave the Sun? The Earth – Moon and Earth – Sun distances are 3.8x105 km and 1.5 × 108 km, respectively. (c) What is the round-trip travel time in seconds for light between Earth and a spaceship at a 6.8 × 107 km distance from Earth? (d) Suppose astronomers observe a supernova about 7300 light-years (ly) distant. How long ago in years did the explosion actually occur?

How many meters are there in 3.2 light year (s), if the speed of light is 3 x 108 m/s. This number may be very large so do not round or truncate your number. Answer:
The Global Positioning System (GPS) relies on very accurate atomic clocks aboard a network of 24 satellites, each of which orbits the Earth in 12 hours. To provide a resolution better than 1 meter on Earth, the clocks must not gain or lose more than 3 ns in 12 hours. That is, the clocks must be accurate to 3 x 10-⁹ s/(12 hr) = 7 × 10-14 The satellites move at a speed v = 3.9 km/s in circular orbits. Is it necessary for GPS receivers on Earth to account for special relativistic effects?
Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54×107 light-years from Earth. If the lifetime of a human is taken to be 70.0 years, a spaceship would need to achieve some minimum speed ?min to deliver a living human being to this galaxy. How close to the speed of light would this minimum speed be? Express your answer as the difference between ?min and the speed of light ?. ?−?min= m/s
A star is 12.2 ly (light-years) from Earth. HINT (a) At what constant speed (in m/s) must a spacecraft travel on its journey to the star so that the Earth–star distance measured by an astronaut onboard the spacecraft is 4.36 ly? m/s (b) What is the journey's travel time in years as measured by a person on Earth?

Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54 × 107 light-years from Earth. If the lifetime of a human is taken to be 85.0 years, a spaceship would need to achieve some minimum speed Umin to deliver a living human being to this galaxy. How close to the speed of light would this minimum speed be? Express your answer as the difference between Umin and the speed of light c. 8.96 ×10¹3 C- Umin m/s Incorrect
A cosmic ray travels 60 km through the earth’s atmosphere in 400 μs, as measured by experimenters on the ground. How long does the journey take according to the cosmic ray?
Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54 x 10' light-years from Earth. If the lifetime of a human is taken to be 75.0 years, a spaceship would need to achieve some minimum speed vmin to deliver a living human being to this galaxy. How close to the speed of light would this minimum speed be? Express your answer as the difference between umin and the speed of light c. C- Umin = m/s
