Answer:
Strain has no units due to simply being the ratio between the extension and original length of a material, so Young's Modulus is measured by the same units as stress... like newtons per square meter (Nm-2) or Pascals (Pa).
From a mathematical point of view, the Schrödinger Equation is a LINEAR partial differential equation, as is a partial differential equation that is defined by a linear polynomial in the solution and its derivatives.
For a linear differential equation, if you got two different solutions and , then the linear combination , where and are scalars, is also a solution.
This also is valid for only one solution (think of the other solution as equal to zero, ). So, as the Schrödinger Equation is a Linear partial differential equation, then if is a solution, then must also be a solution.
This is extremely important for physicist, as let us know that the superposition principle is valid.
Answer:
0.00073
Explanation:
= Fraction of atoms of the element in the excited state
= Fraction of states
T = Temperature = 4471 K
h = Planck's constant =
= Boltzmann constant =
= Wavelength = 407.3 nm
We have the relation
Change in energy is given by
The fraction of atoms of the element in the excited state is 0.00073
Answer:
The moons of the outer planets are made of a mixture of ice and rock but our moon is made of only rock
Explanation:
When it comes to moon the elements silicon, iron & oxygen are classified as rocky materials and the elements carbon, nitrogen & Oxygen-Hydrogen compounds are classified as icy materials.
Our moon is primarily made of Silicon, aluminum, iron, calcium and iron.
Moons of outer planets are made of both icy materials and rocky materials.
Answer:
Condensation causes dew to form on blades of grass. This is because the water molecules react to the grass when it is heated, and the surroundings became cool. The molecules would bring to calm and turn to liquid.
Explanation:
I just took the test
