Light and radio waves travel through a vacuum in a straight line at a speed of very nearly 3.00 ´ 108 m/s. how far is light year (the distance light travels in a year)?

We need to calculate the number of seconds in one year. time = (365 days) (24 hours/day) (3600 seconds/hour) time = 31536000 seconds We can calculate the distance that light travels in this many seconds. distance = speed x time distance = (3.00 x 10^8 m/s) (31536000 seconds) distance = 9.46 x 10^{15} meters A light year is 9.46 x 10^{15} meters

Ihad this on a test i just recently took on edgenuity and got 100%! the answer is b. no acceleration.

Ruth ford over turned thomsons model in 1911 with his well known gold foil experiment in which he demonstrated that the atom has a tiny heavy nucleus rutherford designed an experiment to use the alpha particles emitted by a radio active element as probes to the unseen world of atomic structure. hey hope this
