A car speeding down a 20 foot hill
Answer:
The dimensional formula of the amplitude of a wave is given by,
[ M⁰L¹T⁰ ]
Where,
M = Mass
L = Length
T = Time
Derivation
The amplitude of wave = Maximum displacement
Since, the dimensional formula of displacement = [ M⁰L¹T⁰ ]
Therefore, the amplitude of a wave is dimensionally represented as [ M⁰L¹T⁰ ]
The algebraic expression for the component of the normal force in the vertical direction is Force= product of mass and area.

What is Force?</h3>
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction. Or, there is a specific meaning to the word "force." At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.
