Continental
drift. This Theory was invented by Alfred Wegener.
<span>His
hypothesis was that the continents move relative to each other on the tectonic
plate and so they drift. The drifting and folding of the continents results in pushing
up huge mountains.</span>
Answer:
A.
Explanation:
Our values are defined by,

We can express also in a vectorial way, then
no values in 
Acceleration as follow,

We know that velocity is given by,

We need to calculate for t=3, then




Our mass is 1000Kg, so the momentum is



Answer:
Aphelion: 6404 W/m2
Perihelion: 14978 W/m2
Explanation:
The solar energy flux depends on the solar power output divided by the surface of a sphere with a radius equal to the distance to the Sun.

The distances we need are the aphelion and perihelion of Mercury.
Planetary orbits are ellipses. In an ellipse the eccentricity is related to linear eccentricity and the length of the semi major axis:

Where
e: eccentricity
c: linear eccentricity
a: semi major axis
The linear eccentricity is equal to the distance of the focus of the center of the ellipse.

a = 0.39 AU = 5.83e10 m

In planetary orbits the Sun is in one of the fucuses. With this we can calculate the prihelion and aphelion as:
Ap = a + c = 5.83e10 + 1.22e10 = 7.05e10 m
Pe = a - c = 5.83e10 - 1.22e10 = 4.61e10 m
And the solar energy fluxes will be:
