a steep-sided valley formed by the downward displacement of a block of the earth's surface between nearly parallel faults or fault systems.
Hey There!
When the gas temperature decreases the volume decreases too.

Answer:
1) F = 8.789 10² N, 2) F = 1.5 10⁴ N
Explanation:
We can solve this exercise using Coulomb's law
F =
Knowing that charges of the same sign repel
let's apply this equation to our case
1) the charges are q = - 0.0025 C and the distance between them r = 8 m
we calculate
F = 9 10⁹ 0.0025 0.0025 /8²
F = 8.789 10² N
as the two charges are of the same sign the force is repulsive
2) q₁ = -0.004C and q₂ = -0.003 C with a distance of r = 3.0 m
we calculate
F = 9 10⁹ 0.004 0.003 / 3²
F = 1.5 10⁴ N
The mirror formula for the curved mirrors is 1/f = 1/v + 1/u.
Mirror Formula:
The mathematical expression determining the distance of image and distance of the object from the mirror, without drawing a ray diagram, is known as the mirror formula.
The mirrors whose reflecting surfaces are curved in nature are known as curved mirrors. The curved mirrors are either bulged outwards (convex mirrors) or bulged inwards (concave mirrors).
The mirror formula for the curved mirrors are given as,
here,
f is the focal length of the mirrors.
v is the image distance.
u is the object distance.
Thus, we can conclude that the mirror formula for the curved mirrors is 1/f = 1/v + 1/u.
