Answer:
Aristotle
Explanation:
Aristotle would describe an airplane as "Earthen metal infused with Air and propelled by elemental Fire".
Their presence spread in to the Renaissance from the Antiquity and Early medieval Ages, and was not consistently displaced until the Inquisition and philosophies such as classical physics.Aristotle's views on biblical theory were influenced by physical science. Many of the zoological findings of Aristotle found in his physiology, such as on the octopus ' hectocotyl (reproductive) head, remained incredible until the 19th century.

Answer:
![4.048\times 10^{-7}\ m](https://tex.z-dn.net/?f=4.048%5Ctimes%2010%5E%7B-7%7D%5C%20m)
Explanation:
h = Planck's constant = ![6.626\times 10^{-34}\ m^2kg/s](https://tex.z-dn.net/?f=6.626%5Ctimes%2010%5E%7B-34%7D%5C%20m%5E2kg%2Fs)
c = Speed of light = ![3\times 10^8\ m/s](https://tex.z-dn.net/?f=3%5Ctimes%2010%5E8%5C%20m%2Fs)
E = Energy = ![4.91\times 10^{-19}\ J](https://tex.z-dn.net/?f=4.91%5Ctimes%2010%5E%7B-19%7D%5C%20J)
Wavelength ejected is given by
![\lambda=\dfrac{hc}{E}\\\Rightarrow \lambda=\dfrac{6.626\times 10^{-34}\times 3\times 10^8}{4.91\times 10^{-19}}\\\Rightarrow \lambda=4.048\times 10^{-7}\ m](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7Bhc%7D%7BE%7D%5C%5C%5CRightarrow%20%5Clambda%3D%5Cdfrac%7B6.626%5Ctimes%2010%5E%7B-34%7D%5Ctimes%203%5Ctimes%2010%5E8%7D%7B4.91%5Ctimes%2010%5E%7B-19%7D%7D%5C%5C%5CRightarrow%20%5Clambda%3D4.048%5Ctimes%2010%5E%7B-7%7D%5C%20m)
The maximum wavelength in angstroms of the radiation that will eject electrons from the metal is ![4.048\times 10^{-7}\ m](https://tex.z-dn.net/?f=4.048%5Ctimes%2010%5E%7B-7%7D%5C%20m)
Explanation:
It is given that,
Frequency of diagnostic ultrasound, f = 3.82 MHz = 3820 Hz
The speed of the sound in air, v = 343 m/s
(a) We need to find the wavelength in air of such a sound wave. Let it is given by λ₁
i.e. ![\lambda=\dfrac{v}{\nu}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7Bv%7D%7B%5Cnu%7D)
![\lambda_1=\dfrac{343\ m/s}{3820\ Hz}](https://tex.z-dn.net/?f=%5Clambda_1%3D%5Cdfrac%7B343%5C%20m%2Fs%7D%7B3820%5C%20Hz%7D)
![\lambda_1=0.089\ m](https://tex.z-dn.net/?f=%5Clambda_1%3D0.089%5C%20m)
(b) If the speed of sound in tissue is 1650 m/s .
![\lambda_2=\dfrac{v}{\nu}](https://tex.z-dn.net/?f=%5Clambda_2%3D%5Cdfrac%7Bv%7D%7B%5Cnu%7D)
![\lambda_2=\dfrac{1650\ m/s}{3820\ Hz}](https://tex.z-dn.net/?f=%5Clambda_2%3D%5Cdfrac%7B1650%5C%20m%2Fs%7D%7B3820%5C%20Hz%7D)
![\lambda_2=0.43\ m](https://tex.z-dn.net/?f=%5Clambda_2%3D0.43%5C%20m)
Hence, this is the required solution.
