Three galaxies are aligned along an axis in order A, B, C. An observer in galaxy B is in the middle and observes that galaxies A and C are moving in opposite directions away from him, both with speeds 0.47c. What are the speeds of galaxies B and C as observed by someone in galaxy A? ________c (galaxy B) ______c (galaxy C)

The drawing shows three situations-A, B, and C-in which an observer and a source of electromagnetic waves are moving along the same line, in each case he source ents wave that has a frequency of 4.57 x 1014 Hz. The arrows in each situation denote velocity vectors of the observer and source relative to the ground and have the magnitudes indicated (v or 2v), where the speed v is 2.3 x 106 m/s. Calculate the observed frequency in each of...

Three infinite straight wires are fixed in place and aligned parallel to the z-axis as shown. The wire at (x,y) = (-22 cm, 0) carries current I1 = 3.1 A in the negative z-direction. The wire at (x,y) = (22 cm, 0) carries current I2 = 0.7 A in the positive z-direction. The wire at (x,y) = (0, 38.1 cm) carries current I3 = 6.3 A in the positive z-direction. 1. What is Bx(0,0), the x-component of the magnetic field...

An object is suspended from the ceiling by a spring aligned along a vertical x axis, with upward defined as the positive x direction. When the spring is at its relaxed length, the object is at the origin of the axis. The object is pulled down to position −x1, held at rest, and released. Consider its motion from the instant of release until the instant it returns to −x1. Ignore friction, air drag, and the inertia of the spring. part...
