Answer:
A. Scientists use seismic computer models to measure the atmospheric conditions above the Earth's crust
Explanation:
why would use atmosphere to study the layers of earth? dont think thats possible
Answer:
Explanation:
In this process energy must be conserved. On the initial stage, there will be only gravitational potential energy, while on the final stage there will be only elastic potential energy, so they will be equal. We write this as:
Which is the same as:
So we can obtain our mass from there, and for our values:
Answer:
Onda electromagnética
Explanation:
Las ondas mecánicas requieren un medio material para la propagación, mientras que las ondas electromagnéticas no requieren un medio material para la propagación.
Generalmente, las ondas electromagnéticas se mueven con una velocidad muy alta.
Todas las ondas electromagnéticas se denominan colectivamente luz y tienen una velocidad común de 3 × 10 ^ 8 m / s en el aire.
Ninguna onda mecánica tiene una velocidad tan alta en el aire.
