Why is the symbol for radiation a fan?
The center dot is the "source." The "blades" is the radiation coming from the source. 1 blade and 2 blades does not convey "all directions." 3 blades does and looks more dangerous than concentric circles. 3 blades looks dangerous because many things known to be dangerous come in 3s. Bottom line: It had to look like something. Why are stop signs 8 sided, yield signs triangular, information signs rectangles, and slow signs diamonds?

What are (b) the tip's speed (in meters per second) and (c) the magnitude of its acceleration (in meters per second-squared)? (d) What is the period (in seconds) of the motion? (Note: Using π when appropriate.) Answers please for checking
Answering a question about how the south proliferates racism... her question, my answer?
Q. How does the south proliferate racism? A. Confederate flags, confederate symbols, confederate paraphernalia, confederate monuments and statues, pro confederate literature.. And the fact the official end of Jim Crow, that which is satisfied by legal standards, has only been 54 years ago. And conversations at the dinner table, ranging anywhere from a racially twisted form of Capitalism, trying to brainwash the kid... all the way to recruitment into the KKK and the Neo Nazis. All kinds of ways.
