Answer:
Las Zonas de Expansión son aquellos lugares donde las placas de la corteza terrestre se están separando, impulsadas por las corrientes ascendentes del manto superior, dando lugar a la salida de magma procedente de interior.

Answer:
circle vs eclipse - down below!!
Explanation:
a circle has the same distance between a center, but an eclipse does not have the same distance between a center. AND, an circle has a fixed radius that stays solid, but a eclipse does not.
Answer:
It's a global navigation satellite system that provides location, velocity and time synchronization. GPS is everywhere. You can find them in your car, phone, and watch.
Answer:
False
Explanation:
Mercury and Venus are the planets without orbiting satellite in our Solar System.
Earth has just one satellite and Mars has two of them.
Among the giant planets the number of satellites is really bigger, for example Jupiter has 67 and Saturn 62; Uranus has 27 and Neptune has 14.
The free body diagram consists of:
1) Weight force, which is a vertical arrow downward
2) A Normal force that is perpendicular to the ramp.
The Normal force can be decomposed in a vertical component and an horizontal component.
The vertical component, Ny, must equal the weight force, due to equilibrium (rest) condiition =>
Ny = weight = m*g = 5.5kg*9.8m/s^2 = 53.9 N
By geometry the vertical component of the Normal force, Ny is such that
cos (angle) = N / Ny => N = Ny * cos(angle)
=> N = 53.9N * cos(angle)
Now use that equation for each option:
a) 0 ° => N = 53.9N * cos(0) = 53.9N
b) 12° => N = 53.9 * cos(12) = 52.7N
c) 25° => N = 53.9 * cos(25) = 48.9N
d) 45° => N = 53.9 * cos(45) = 38.1N
