The normal force is always (underline, bold) is always perpendicular to the surface an object is sitting on. If the object is on an inclined plane, then the normal will not be vertical but it will be perpendicular to the angle of the incline.
The diagram below (left) shows a normal force (GH) that is not vertical, but it is perpendicular to the surface. The object on the right is the more usual normal a mass on a table top.
The vertical line on the right is the normal and it points up.
Explanation:
An acid is a substance that interacts with water to produce excess hydroxonium ions, H₃O⁺ in an aqueous solution.
The hydroxonium ions formed by the chemical bonding between the oxygen of water molecules and the protons released by the acid due to its excess ionization.
For example:
HCl + H₂O ⇄ H₃O⁺ + Cl⁻
acid water hydroxonium chloride
A base is a substance that interacts with water to yield excess hydroxide ions, OH⁻ in an aqueous solutions:
NH₃ + H₂O ⇄ NH₄⁺ + OH⁻
Ammonia water ammonium hydroxide
These explanations are based on the arrhenius theory.

Answer:
That's not a question. And we have that already its called a hybrid. They have a gas engine with a fuel tank and a battery to save fuel.
Explanation:
Make it a question.
Answer:
a. slope=rise/run
rise=2
run=10
slope=2/10
slope=1/5
used point (0,0) and (10,2)
slope(m)=1/5
b. area= 0.5bh
0.5×50s×10m/s
a=25s×10m/s
a=250m
c.the area represents the total distance traveled after 50s by the toy
the slope represents the acceleration of the toy
the unit of slope is m/s²
slope=rise/run
slope(m)=(2m/s)÷10s
m=(2/10)m/s/s
m=(1/5)m/s²
.=0.2m/s²
