Astar is moving away from the earth at a speed of 0.60 c as measured in an inertial system s, at rest with respect to the earth. at time t-0, when the star is 109 ly away as measured in s, the following two events occur simultaneously as observed in s: 1-a bomb explodes nearby the earth 2- a bomb explodes on the moving star. give the space and time coordinates for events 1 and 2 as observed in s', which is at rest with respect to the star, according to a) galilean transformations and b) lorentz transformations.

Biased means unfair but that's all ik

The answer which is not a detail carson used to describe the pool in the cave at low tide is b.  hundreds of periwinkles browse the branches and roots of the trees. 

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
