Answer:
E = 1000 x
Explanation:
The electric potential and the electric field are related by the formula
dV = - E . dx
Bold represents vectors.
The point represents the scalar product, in this case we calculate the electric field in the x-axis and the potential is also in this axis so the scalar product is reduced to the algebraic product
E = dV /dx
Let's make the derivative
E = - 2ax
Let's replace the values
E = -2 (-500) x
E = 1000 x
Answer:
B). Cell wall
Explanation:
a cell wall gives the plant cell its rigid box like shape, which animal cells do not have since they do not have cell walls.
D- cation, When an atom loses a electron it becomes an ion but the result is called a cation. Then when electrons are gained it’s a anion.
