Answer:
B
Explanation:
it's converts electrical energy to mechanical energy.
Waterfalls are created when a river flows following a descending rapid slope. The waterfall, then, flows from the source (where it starts) to the mouth (where it ends).
Waterfalls are created when the erosion of the rocks at the bottom of the slope is more powerful than the erosion of the rocks on the top.
After many years the water is able to erode the rocks on the top as well, and the waterfall slowly disappears.
Therefore the options that apply are:
b) waterfalls move towards their mouth;
c) the top or cap rock is resistant to erosion;
<span>f) waterfalls indicate a youthful river </span>
Answer:
-7.03645640575 Nm²/C
2.34548546858 Nm²/C
Explanation:
S = Surface area
Electric flux through the base is given by
The electric flux through the base is -7.03645640575 Nm²/C
Inside the tetrahedron there is no charge so total flux will be zero
The electric flux through the sides is 2.34548546858 Nm²/C
