Simultaneous? in a reference frame s two very evenly matched sprinters are lined up a distance l apart along the x axis for a race parallel to the y axis. two starters, one beside each runner will fire their pistols at lightly different times, giving a handicap to the faster of the two sprinters. the time difference in the frame s is t (a) for what range of time differences will there be a reference frame s in which there is no handicap, and for what range of time difference is there a true (not apparent) handicap. (b) determine the lorentz transformation to the frame s appropriate for each of the two possibilities in part (a), finding the velocity of s relative to s

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.
