Answer:
(we need the mass of the astronaut A)
Explanation:
We can solve this by using the conservation law of the linear momentum P. First we need to represent every mass as a particle. Also we can simplify this system of particles by considering only the astronaut A with an initial speed of 0 m/s and a mass
and the IMAX camera with an initial speed
of 7.5 m/s and a mass
of 15.0 kg.
The law of conservation says that the linear momentum P (the sum of the products between all masses and its speeds) is constant in time. The equation for this is:
By the law of conservation we know that
For (final linear momentum) we need to treat the collision as a plastic one (the two particles stick together after the encounter).
So:
Answer:
The intensity I₂ of the light beam emerging from the second polarizer is zero.
Explanation:
Given:
Intensity of first polarizer = Io/2
For the second polarizer, the intensity is equal:
<em>An electron has the same amount of energy in all orbitals is not true</em>
In an atom there are levels of energy in the skin and sub skin.
- This energy level is expressed in the form of electron configurations.
Writing electron configurations starts from the lowest to the highest sub-shell energy level.
So electrons that occupy the orbitals in the lowest sub-skin have the lowest energy level
- In the principle of Pauli's prohibition it was stated that there are no two electrons in one atom that can have the same four quantum numbers.
So suppose that there are two electrons occupying one orbital can have the same main quantum number (n), azimuth (l) and magnetic (m), then the last quantum number that is the quantum spin number (s) must be different.
So that the two electrons are different from just the quantum spin number, even though the other quantum numbers are the same.
So in one orbital only a maximum of 2 electrons is occupied, because if there is a third electron, this third electron will have the same quantum spin number as the previous electron
- The electron cloud is a visual representation of the location of electrons in an atom.
Orbital is the place around the nucleus where electrons may be found
Electron clouds show the state of electrons in their orbitals
So electron clouds can show the condition of all orbitals in an atom
The lowest energy level of an electron occupies a sub-skin of 1s which has only one orbital
Charging electrons in the sub skin uses the following sequence:
1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.
