Two waves traveling in opposite direction produce a standing wave. The individual wave functions are y1=4sin(3x-2t) y2=4sin(3x+2t) A) find the amplitude of the simple harmonic motion of the element of the medium located at x=2.3.
B) find the position of the nodes and anti nodes if one end of the string is at x=0.
C) what is the maximum value of the position in the simple harmonic motion of an element located at an anti node?​

In what direction does the medium move relative to the direction of the wave? explain.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
