Edit: You do mean Ridge?
Rocks near Mid-Ocean Ridge are younger than rocks near the trenches.
Seismic data shows oceanic crust is sinking into the mantle at the trenches.
Matching bands of magnetic rock are found on either side of the Ridge. Earth's magnetic fields change these bands over time.
Force on electron due to electric field is given by



now the acceleration is given by



so above is the magnitude of acceleration and its direction is opposite to field as electron is negatively charged so direction is towards SOUTH
Because of Surface tension
Answer: 4.6 years
Explanation:
According to Kepler’s Third Law of Planetary motion <em>“The square of the orbital period
of a planet is proportional to the cube of the semi-major axis
(size) of its orbit”:
</em>
<em />
(1)
However, if
is measured in Earth years, and
is measured in astronomical units (unit equivalent to the distance between the Sun and the Earth), equation (1) becomes:
(2)
Knowing
and isolating
from (2):
(3)
(4)
Finally:
This is Ceres' orbital period
Answer:
(a) Magnitude =3.18 km
(a) Angle =28.2°
Explanation:
(a) To find magnitude of this vector recognize

Use Pythagorean theorem

(b)To find the angle use the trigonometric property
