Answer:
the third one T-W
Explanation:
the direction of the Tension and weight are opposite
They compress or expand depending on amount of pressure or depending on the temperature
Answer:
Acceleration
Explanation:
I think so & hope it will help yuh!
I believe you're talking about displacement. It's a directional vector that depicts the movement of a point between two instances.
Answer:
Y = V / f where Y equals wavelength
4 Y1 = V / f1 for a closed pipe the wavelength is 1/4 the length of the pipe
2 Y2 = V / f2 for the open pipe the wavelength is 1/2 the length of the pipe
Y1 / Y2 = 2 = f2 / f1 dividing equations
f2 = 2 f1
the new fundamental frequency is 2 * 130.8 = 261.6
(The new wavelength is 1/2 the original wavelength so the frequency must double to produce the same speed.
