The distance to a particular star, as measured in the earth’s frame of reference, is 7.87 ly (1 light year is the distance light travels in 1 year). A spaceship leaves earth headed for the star, and takes 3.96 yr to arrive, as measured by passengers on the ship. 1. How long does the trip take, according to observers on earth? Express your answer with the appropriate units. (t = ? yr) 2. What distance for the trip do passengers...

These are the answers, please provide the work for the calculation 1. Two cells that subdivide on Earth every 10.0s start from the Earth on a journey to the Sun (1.5 x 1011 m away) in a spacecraft moving at 0.850c. How many cells wil exist when the spacecraft crashes into the Sun? Earth time is 588s. Spacecraft time is 310s or 31 cycles of division. 2312.1x 10 cells at the end of the journey. 2. As a spacecraft moving...
