Ejemplos de fuerzas
En la naturaleza, las fuerzas fundamentales son la gravedad, la fuerza nuclear débil, la fuerza nuclear fuerte, la fuerza electromagnética y la fuerza residual. La fuerza fuerte es lo que mantiene unidos protones y neutrones en el núcleo atómico.
Answer:
I agree I think it is 90 :)
Explanation:
Answer:
Igneous rocks are formed from cooled magma but metamorphic rocks are formed by temperature and pressure changes inside the Earth
Explanation:
Igneous rock , formed by the cooling of magma (molten rock) inside the Earth or on the surface. ... Metamorphic rocks, formed by temperature and pressure changes inside the Earth. All three types of rock make up the Earth's lithosphere, the outermost layer.
The statement underlying mantle layer is molten where convection currents cause the movement of the lithospheric plates explains the movement of these lithospheric plates.
<h3>What is tectonic plate movement? </h3>
The theory discusses how Earth's surface is composed out of rigid slabs of <em>rock</em> that are known as plates. These <u>large pieces </u>of plates under the Earth's surface are regarded as the lithosphere.
Therefore, convection currents that appear in the mantle lead to movements in the plates due to the flow of current to heat up the mantle.

Answer: 1) Angular separation equals 0.0000031 degrees
2) Angular separation in arc -seconds equals 0.011156"
Explanation:
For 2 stars separated by a distance 'S' and at a distance 'D' from the earth the angular separation in radians is given
Applying values we get
Now we know that 'π' radians equals 180 degrees thus the above value in degrees shall be equal to
2)
The angular separation in arc- seconds is given by
