0an air-pressure signal at 5 atm and 50.c is fed through a 1.0-mm-diameter line cm3. having a length of 0.8 m, and is connected to a transducer volume of 3 calcu late the natural frequency and damping ratio of this system. by how much will a pressure signal having a frequency one-half the natural frequency be attenuated?

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.

Awoman holds a book by placing it between her hands such that she presses at right angles to the front and back covers. the book has a mass of m = 1.8 kg and the coefficient of static friction between her hand and the book is μs = 0.67. no attempt 50% part (a) what is the weight of the book, fgb in newtons?

How is zig zagging a form of acceleration?
