Light incident on a pair of slits produces an interference pattern on a screen 2.30 m from the slits. If the slit separation is 0.0157 cm and the distance between adjacent bright fringes in the pattern is 0.769 cm, what is the wavelength of the light? [Hint: Is the small angle approximation justified?]

In 1924, Louis de Broglie postulated that particles such aselectrons and protons might exhibit wavelike properties. Histhinking was guided by the notion that light has both wave andparticle characteristics, so he postulated that particles such aselectrons and protons would obey the same wavelength-momentumrelation as that obeyed by light: \lambda = h/p, where lambda isthe wavelength, p the momentum, and h Planck's constant.

a. Find the de Broglie wavelength lambda for an electron moving ata speed of 1.00 \times 10^6 \; {\rm m/s}. (Note that this speed islow enough that the classical momentum formula p=mv is stillvalid.) Recall that the mass of an electron is m_{\rm e} =9.11\times 10^{-31}\; {\rm kg}, and Planck's constant is h = 6.626\times 10^{-34}\; {\rm J \cdot s}.
Express your answer in meters to three significant figures.
lambda =7.270×10-10 \rm m

b. Find the de Broglie wavelength lambda of a baseball pitched at aspeed of 43.7 m/s. Assume that the mass of the baseball is 0.143\;{\rm kg}.
Express your answer in meters to three significant figures
lambda =1.06×10-34 \rm m

c. Consider a beam of electrons in a vacuum, passing through a verynarrow slit of width 2.00 \;\mu{\rm m}. The electrons then headtoward an array of detectors a distance 1.076 m away. Thesedetectors indicate a diffraction pattern, with a broad maximum ofelectron intensity (i.e., the number of electrons received in acertain area over a certain period of time) with minima of electronintensity on either side, spaced 0.518 cm from the center of thepattern. What is the wavelength lambda of one of the electrons inthis beam? Recall that the location of the first intensity minimain a single slit diffraction pattern for light is y=L \lambda /a,where L is the distance to the screen (detector) and a is the widthof the slit. The derivation of this formula was based entirely uponthe wave nature of light, so by de Broglie's hypothesis it willalso apply to the case of electron waves.
Express your answer in meters to three significant figures.

Hi tried your suggestions for the previous question see link

By the way it works fine when connecting to Windows, Chrome and Edge.

Anyway I'm doing this from home not from the workplace or school.

I also deleted *.gradle directory that didn't resolve the issue.

Using Gradle version 8.4 see picture. Also I noticed when I create new flutter device from command prompt it I get a pubspec.yaml, but when I do it from the latest Android Studio Giraffe it doesn't create a pubspec.yaml. So that's the reason why I create new flutter device form command prompt.

A rocket is launched from the surface of the Earth with an initial velocity of 300 m/s upward. The rocket's acceleration due to gravity is approximately 9.8 m/s29.8m/s2, and it is also subject to air resistance, which can be modeled by the equation �air=−��Fair​=−kv, where �airFair​ is the air resistance force in newtons, �k is a positive constant, and �v is the velocity of the rocket in m/s. Source: helpinhomework.org 

a) Determine the rocket's velocity as a function of time, �(�)v(t), given that the air resistance is proportional to its velocity.

b) Find the time it takes for the rocket to reach its maximum height.

c) Calculate the maximum height the rocket reaches above the Earth's surface.

d) Determine the rocket's velocity as a function of time on its way down to the Earth, taking into account the air resistance.

e) Find the time it takes for the rocket to return to the surface.

f) Calculate the total time of flight for the rocket.
