A shift of one fringe in the Michelson-Morley experiment corresponds to a change in the round-trip travel time along one arm of the interferometer by one period of vibration of light (about 2 โ 10โ15 s) when the apparatus is rotated by 90ยฐ. t = 2 tacross = 2L c2โu2 = 2L c 1โ u2/c2 , what velocity through the ether would be deduced from a shift of one fringe? (Take the length of the interferometer arm to be 12 m.)

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4ร10 to the power of 23 kg, radius = 3.4ร10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3ร10 to the power of 8 km from the sun.)
