Answer:
W=561.41 J
Explanation:
Given that
m = 51 kg
μk = 0.12
θ = 36.9∘
Lets F is the force applied by man
Given that block is moving at constant speed it mans that acceleration is zero.
Horizontal force = F cos θ
Vertical force = F sinθ
Friction force Fr= μk N
N + F sinθ = m g
N = m g - F sinθ
Fr = μk (m g - F sinθ)
For equilibrium
F cos θ = μk (m g - F sinθ)
F ( cos θ +μk sinθ) = μk (m g
Now by putting the values
F ( cos 36.9∘ + 0.12 x sin36.9∘)=0.12 x 51 x 10
F= 70.2 N
We know that Work
W= F cos θ .d
W= 70.2 x cos 36.9∘ x 10
W=561.41 J
Explanation:
(a) The Schrodinger's wave function represent the position of a particle at a particular instant of time. It is also known as the probability amplitude. It is also used to find the location of a particle.
(b) The width of a potential well, ![l=5\ A=5\times 10^{10}\ m](https://tex.z-dn.net/?f=l%3D5%5C%20A%3D5%5Ctimes%2010%5E%7B10%7D%5C%20m)
For first energy level, n = 1
Energy in infinite potential well is given by :
![E=\dfrac{n^2h^2}{8ml}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7Bn%5E2h%5E2%7D%7B8ml%7D)
![E=\dfrac{(1)^2\times (6.63\times 10^{-34})^2}{8\times 9.1\times 10^{-31}\times 5\times 10^{10}}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B%281%29%5E2%5Ctimes%20%286.63%5Ctimes%2010%5E%7B-34%7D%29%5E2%7D%7B8%5Ctimes%209.1%5Ctimes%2010%5E%7B-31%7D%5Ctimes%205%5Ctimes%2010%5E%7B10%7D%7D)
E = 0.0120 Joules
For second energy level, n = 2
![E=\dfrac{n^2h^2}{8ml}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7Bn%5E2h%5E2%7D%7B8ml%7D)
![E=\dfrac{(2)^2\times (6.63\times 10^{-34})^2}{8\times 9.1\times 10^{-31}\times 5\times 10^{10}}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B%282%29%5E2%5Ctimes%20%286.63%5Ctimes%2010%5E%7B-34%7D%29%5E2%7D%7B8%5Ctimes%209.1%5Ctimes%2010%5E%7B-31%7D%5Ctimes%205%5Ctimes%2010%5E%7B10%7D%7D)
E = 0.0483 Joules
For third energy level, n = 3
![E=\dfrac{n^2h^2}{8ml}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7Bn%5E2h%5E2%7D%7B8ml%7D)
![E=\dfrac{(3)^2\times (6.63\times 10^{-34})^2}{8\times 9.1\times 10^{-31}\times 5\times 10^{10}}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B%283%29%5E2%5Ctimes%20%286.63%5Ctimes%2010%5E%7B-34%7D%29%5E2%7D%7B8%5Ctimes%209.1%5Ctimes%2010%5E%7B-31%7D%5Ctimes%205%5Ctimes%2010%5E%7B10%7D%7D)
E = 0.108 Joules
Hence, this is the required solution.

Answer:
45 degrees
Explanation:
The textbooks say that the maximum range for projectile motion (with no air resistance) is 45 degrees.
An ocean current<span> is any more or less permanent or continuous, directed movement of </span>ocean<span> water that flows in one of the Earth's </span>oceans<span>. The </span>currents<span> are generated from the forces acting upon the water like the earth's rotation, the wind, the temperature and salinity differences and the gravitation of the moon.
