The air temperature is 25 °C and an air column carries a standing sound wave at a frequency of 340 Hz. What is the
length of the air column, which is closed at one end, if it is
designed for the third harmonic? K

i need the answer to this too but idk it ; -;

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y
