<span>The correct answer is option (d) i.e. When you return to Earth after a space mission, you will be aged slightly less than the person who remained on Earth.</span>
<span> The exact age difference depends on the details of the journey. This can be explained by the time dilation concept of Relativity.</span>
Answer:
θ = 34.77°
Explanation:
From diffraction equation:
![m\lambda = dSin\theta](https://tex.z-dn.net/?f=m%5Clambda%20%3D%20dSin%5Ctheta)
where,
m = order of diffraction
λ = wavelength of light used
d = slit separation
θ = angle
Therefore, for initial case:
m = 2
λ = 600 nm = 6 x 10⁻⁷ m
d = slit seperation = ?
θ = angle 20°
Therefore,
![(2)(6\ x\ 10^{-7}\ m)=d(Sin\ 20^o)\\\\d = \frac{12\ x 10^{-7}\ m}{0.342}\\\\d = 3.5\ x\ 10^{-6}\ m](https://tex.z-dn.net/?f=%282%29%286%5C%20x%5C%2010%5E%7B-7%7D%5C%20m%29%3Dd%28Sin%5C%2020%5Eo%29%5C%5C%5C%5Cd%20%3D%20%5Cfrac%7B12%5C%20x%2010%5E%7B-7%7D%5C%20m%7D%7B0.342%7D%5C%5C%5C%5Cd%20%3D%203.5%5C%20x%5C%2010%5E%7B-6%7D%5C%20m)
Now, for the second case:
m = 5
λ = 600 nm = 6 x 10⁻⁷ m
d = slit seperation = (1.5)(3.5 x 10⁻⁶ m) = 5.26 x 10⁻⁶ m
θ = angle = ?
Therefore,
![(5)(6\ x\ 10^{-6}\ m) = (5.26\ x\ 10^{-6}\ m)Sin\theta\\\\Sin\theta = \frac{(5)(6\ x\ 10^{-7}\ m)}{(5.26\ x\ 10^{-6}\ m)}\\\\\theta = Sin^{-1}(0.5703)](https://tex.z-dn.net/?f=%285%29%286%5C%20x%5C%2010%5E%7B-6%7D%5C%20m%29%20%3D%20%285.26%5C%20x%5C%2010%5E%7B-6%7D%5C%20m%29Sin%5Ctheta%5C%5C%5C%5CSin%5Ctheta%20%3D%20%5Cfrac%7B%285%29%286%5C%20x%5C%2010%5E%7B-7%7D%5C%20m%29%7D%7B%285.26%5C%20x%5C%2010%5E%7B-6%7D%5C%20m%29%7D%5C%5C%5C%5C%5Ctheta%20%3D%20Sin%5E%7B-1%7D%280.5703%29)
<u>θ = 34.77°</u>
Answer: E) Acceleration, net force
Explanation: In order to explain this problem we have to consirer that the uniform circulat motion has constant angular velocity (ω) and the vector velocity is changed its direction for any point that cover the circle but its modulus is contant and its value is v=ω*R. In order to ensure these conditions, the net force also the accelaration called centripetal must point to the center of the circular trajectory.
I hope it helps! good luck in chem!
Question isn’t clear
If it’s asking the no of electrons then -
No of electrons =no of protons in an atom of a element ....therefore there are 11 electrons
