An open organ pipe has a fundamental frequency of 256Hz at room temperature (68oF). a.) What is the length of the pipe?
b.)If the temperature of the air went up to 90oF, what would be the new fundamental frequency?

i guess it’s a and b

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

the maxium height is 34m/s
