<span>Waves erode through forcing air bubbles into tiny cracks in rocks (hydraulic action), and also by abrasion, whereby it causes rocks to be hurled against rock faces.

Answer:
Explanation:
Consider that F (any function) <0 .
u(x,y) is a coontinuous function in the closed interval or region R.
Let us consider a point (p,q) that is inside the region and it is a maximum point.
Then it should be must
uxx (p,q) <0 where uxx means double differentiation
and uy(p,q) >0
Since ux(p,q) = 0 = uy(p,q) where ux and uy means single differentiation with respect to x and y respectively.
Say, Maximum limits of the region is T
therefore q<T
then uy (p,q) = 0 if q<T
if q = T then
point (p,q) = (p,T) will be on the boundary of R then we claim that
uy(p,q) >0
Similarly for the minimum also it will work
Answer:
(-5, 2)
Explanation:
We must remember that the components of a given point in a two-dimensional space are the points on an x & y coordinate axis
A = (-5, 8) = (x, y)
B = (0, -6) = (x, y)
Since the vector operation is a sum, we simply have to sum the components of x and the components of y.
A + B = (-5 + 0) , (8 + (-6))
A + B = (-5, 2)
Inertia- a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
