An advanced computer sends information to its various parts viainfrared light pulses traveling through silicon fibers. To acquiredata from memory, the central processing unit sends a light-pulserequest to the memory unit. The memory unit processes the request,then sends a data pulse back to the central processing unit. Thememory unit takes 0.5 ns to process a request.If the information has to be obtained from memory in 2.0 ns, whatis the maximum distance the memory unit can be from the centralprocessing unit?I have already tried 22.5, 60, 37.5, and 45 and these answers werewrong. I only have two tries left so please help!!
Lunar astronauts placed a reflector on the moon's surface, off which a laser beam is periodically reflected. The distance to the moon is calculated from the round trip time.
(a) To what accuracy in meters can the distance to the moon be determined if this time can be measured 0.1 nsย
(b) What percentage accuracy is this, given the average distance to the moon is 384400km.
