Answer:
here,
<y +<z = 150 ° ( sum of two sides of interior angle is equal to exterior angle)
or,65°+<x=150°
or, <x=150°-65°
or, <X = 85°
Now,
<x +<y+<z=180° [ the sum of three angles of a triangle is 180°]
or, < x+65°+85°=180°
or, <x =180°-150°
or,< x=30°
Then,
<x+<y=<z
30° +65° =95 °
or, 180° -95° = 85 °
To get <XZW,
180° - 85 ° = 95°[ The exterior angle is equal to the differnce of 2 interior angles through 180 °]
The three main particles of an atom are: electron, proton, and neutron.
This table shows the differences on the three properties: location, charge, and mass, for the three particles:
particle location charge (C) mass (g)
electron space around the nucleus - 1.6 * 10^ -19 9.11 * 10^ -28
proton nucleus + 1.6 * 10^ -19 1.673 * 10 ^ - 24
neutron nucleus 0 1.675 * 10 ^ 24
It is important to drive some conclusions that permit you to have a better picture ot these particles and their differences:
1) electrons are in the space around the nucleus in regions called orbitals. Those are not orbits, because the electrons are not orbiting the nucleous.
2) Both protons and neutrons are inside the nucleus of the atom.
3) Electrons and protons have opposite charges of the same magnitude. The number of protons and electrons in an atom are equal, that is why they are neutral. The neutrons, which are inside the nucleus, with the protons, does not have charge.
4) The mass of the protons and the neutrons are almost equal.The difference does not count for the usual calculations.
5) The mass of one electron is 1 / 1840 times the mass of one proton. A very low quantity.
6) Electron is a fundamental particle (it is not formed by other particles).
7) Protons and neutrons are not fundamental particles. They are formed by quarks.
Wien's displacement law states that the black-body radiation curve for different temperatures will peak at different wavelengths that are inversely proportional to the temperature.
Answer:
porque sin paz no habría nada solo guerra
Explanation:
<em>Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.</em>
