well using time dilation equation. Delta T is equal to delta. T p divided by the square root off one minus. We squared, divided by C square. Well, he appropriate time is, uh, 15 years divided by square root off one minus. We leave 70% which is, uh, 0.700 all square. See, school gets canceled with C square, and therefore Delta T is equal to 21 point, uh, zero years. Well, this is part of it. Now, let's to part B. Well, using our disk unsteady is equal to speed multiplied by time. Well, speeding this case is 0.770 times the speed of light multiplied by, uh, T is a 21 point, uh, zero years and this is equal to a 14 point are seven light years. So distances, 14.7 light years. Uh, bark. See, uh, here, using a deep prime is equal to wheat multiplied with proper time. And therefore, D prime is well, d prime physical to multiply delta T p. And the 0.7 00 times the speed of light multiplied by proper time is 15 years. And thus D prime is equal to 10.5 light years. Okay, No party Well in body minutes. Calkins don't all ears us. A total years is, uh, to 21.0 years was, uh, 14.7 here, which gives us a 35.7 years.
