The amplitude of a standing sound wave in a long pipe closed at the left end is sketched below. The vertical axis is the maximum displacement of the air, and the horizontal axis is along the length of the pipe. What is the harmonic number for the mode of oscillation illustrated? Submit Answer Tries 0/12 The length of the pipe is 0.350 m. What is the pitch (frequency) of the sound? Use 340 m/s for the speed of sound in air. Submit Answer Tries 0/12 The pipe is now held vertically, and a small amount of water is poured inside the pipe. The first harmonic frequency is then measured to be 267.1 Hz. Measuring from the bottom of the pipe, what is the level of the water?

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

happy to

pls mark as brainliest

positive reinforcement? ?

d) physical means can be used to separate the components of air.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
