- A I squar frame has sides that measure 2.45m when it is at rest. What is the area of the frame when it moves parellel to one of its diagonal with a m² speed of 0.86.c as indicated in the figure? >V.arrow_forwardAn astronent travels to a distant star with a speed of 0.44C relative to Earth. From the austronaut's point of view, the star is 420 ly from Earth. On the return trip, the astronent travels speed of 0.76c relative to Earth. What is the distance covered on the return trip, as measured by the astronant? your answer in light-years. with a Give ly.arrow_forwardstar by spaceship Sixus is about 9.00 ly from Earth.
