The galaxy Palioxis is receding from the Milky Way at a speed of 0.35c. Another galaxy, Euthenia, is receding from the Milky Way in exactly the opposite direction, but at a speed of 0.45c. (a) For an observer in Palioxis, how fast is the Milky Way receding from them? Explain from them? Explain (b) For an observer in Palioxis, how fast is Euthenia receding f Imagine two muons, symbol μ-, moving towards each other with equal and opposite speeds. If...

Consider two toy cars. Car A starts from rest and speeds up with constant acceleration for a time tA until it reaches a speed of vA and then continues to travel at this speed. At the moment car A reaches its maximum speed, car B, starting at rest from the same point that car A started from, speeds up with constant acceleration aB. a) Make a freehand plot of the speed of each car as a function of time. Label...

A distant galaxy is simultaneously rotating and receding from the earth. As the drawing shows, the galactic center is receding from the earth at a relative speed of UG = 1.70 x 106 m/s. Relative to the center, the tangential speed is vT = 5.00 105 m/s for locations A and B, which are equidistant from the center. When the frequencies of the light coming from regions A and B are measured on earth, they are not the same and...

Two spaceships approach Earth with equal speeds, as measured by an observer on Earth, but from opposite directions. A meterstick on one space- ship is measured to be 60 cm long by an occupant of the other spaceship. What is the speed of each spaceship, as measured by the observer on Earth? (A) 0.4c (B) 0.5c (C) 0.6c (D) 0.7c (E) 0.8c

A distant galaxy is simultaneously rotating and receding from the earth. As the drawing shows, the galactic center is receding from the earth at a relative speed of uG = 2.20 × 106 m/s. Relative to the center, the tangential speed is vT = 0.550 × 106 m/s for locations A and B, which are equidistant from the center. When the frequencies of the light coming from regions A and B are measured on earth, they are not the same...

As seen from the Earth, the distance from Earth to the Sun is 1.50 x 10 meters. A certain particle travels that distance in only 9.62 minutes. Answer the three questions below, using three significant digits. Part A: What is the speed of the particle (v) as seen from Earth? DE m/s Part B: From the perspective of the particle, how much time (App) does it take to reach the Earth? (Note: Specify your answer in minutes.) (Alp) = min...

As seen from earth (rest frame S) two Death Stars (A and B) are approaching in opposite directions, each with speed 0.9c relative to earth (frame S). Find the velocity of Death Star B, as measured by the pilot of Death Star A. [Hint: Consider a coordinate system S' traveling along with Death Star A; your problem is then to find the velocity u' of Death Star B relative to S’, knowing its velocity u relative to S.] 0.9c 0.9c...
