Sunspots vary in number as a function oftime, exhibiting an approximately 11-year cycle. Galileo made thefirst European observations of sunspots in 1610, and daily observations were begun in Zurich in 1749. At the present time we are wellinto the 24th observed cycle. What is the frequency of the sunspotcycle? Give your answer in Hz

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
