Plate tectonics<span>is a </span>scientific theory<span> that describes the large-scale motion of </span>Earth<span>'s </span>lithosphere<span>. This theoretical model builds on the concept of </span>continental drift<span> which was developed during the first few decades of the 20th century. The </span>geoscientific<span> community accepted plate-tectonic theory after </span>seafloor spreading was validated in the late 1950s and early 1960s.<span>The lithosphere, which is the rigid outermost shell of a planet (the crust and upper mantle), is broken up into </span>tectonic plates<span>. </span>
Answer:
E = 1.50 × 
V/m
Explanation:
given data
B = 0.50 T
solution
we know that energy density by the magnetic field is express as
...............1
and
energy density due to electric filed is
...............2
and here 
so that
E = 
...................3
put here value and we get
E = 3 × × 0.50
E = 1.50 × V/m
It is either the mass or density, I believe it is 3 density tho but it could be mass good luck:)
Answer:
4 Newton
Explanation:
F=ma therefore 2kg*2m/s/s=4 Newton
Answer:
The horizontal forces (Cols 2 & 3) balance for W and Y.
The vertical forces (Cols 1 & 4) also balance for W and Y.
This is not true for either X (unbalanced horizontal forces) or
Z (also unbalnced horizontal forces)
