Explanation:
The statistic shows the fastest roller coasters in the world in 2021, by top speed
Answer:
The length of the pipe A is
= 0.4763 m & the length of the pipe B is
0.357 m
Explanation:
Fundamental frequency = 360 Hz
Velocity = 343 ![\frac{m}{s}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7Bs%7D)
(a). Length of the pipe is given by
![L = \frac{V}{2 f}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7BV%7D%7B2%20f%7D)
Put all the values in above equation we get
![L = \frac{343}{2 (360)}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7B343%7D%7B2%20%28360%29%7D)
= 0.4763 m
(b). Given that
The third harmonic of organ pipe B = the second harmonic of pipe A
![\frac{n_B}{4L_B} = \frac{n_A}{2L_A}](https://tex.z-dn.net/?f=%5Cfrac%7Bn_B%7D%7B4L_B%7D%20%3D%20%5Cfrac%7Bn_A%7D%7B2L_A%7D)
Thus
![L_B = \frac{2 n_{B} L_A }{4n_A}](https://tex.z-dn.net/?f=L_B%20%3D%20%5Cfrac%7B2%20n_%7BB%7D%20L_A%20%7D%7B4n_A%7D)
Put all the values in above formula we get
![L_B = \frac{2 (3)(0.4763) }{4(2)}](https://tex.z-dn.net/?f=L_B%20%3D%20%5Cfrac%7B2%20%283%29%280.4763%29%20%7D%7B4%282%29%7D)
0.357 m
Therefore the length of the pipe A is
= 0.4763 m & the length of the pipe B is
0.357 m
Answer:
the axes of the two polarizers are aligned, the angle between this axis must be zero
Explanation:
Polarizers are anisotropic systems where absorption is selective in each axis, in this case they indicate that on an axis they let 100% pass and perpendicular to this axis no light passes.
The first polarizer defines a direction of light that of its axis, it is said that the light is polarized, when this light reaches the second polarized, so that it can pass the axis must be in the direction of the polarized beam.
In summary, the axes of the two polarizers are aligned, the angle between this axis must be zero
The answer is B hope this helps
Answer:
Accordingly, when our Sun comes up short on hydrogen fuel, it will grow to end up a red monster, puff off its external layers, and after that settle down as a minimal white small star, at that point gradually chilling off for trillions of years.
All incredible, in the long run — in around 5 billion years — our sun will, as well. When its supply of hydrogen is depleted, the last, sensational phases of its life will unfurl, as our host star extends to wind up a red goliath and afterward shreds its body to consolidate into a white smaller person
