Answer:
The coefficient of kinetic friction is 0.51.
Explanation:
Given that,
Applied force, F = 75 N
Mass of a box, m = 15 kg
The acceleration of the box is 3 m/s²
We need to find the coefficient of kinetic friction. It is given by the formula as follows :

Where,
, is the normal force

So, the coefficient of kinetic friction is 0.51.
Hot air always goes for the top of air and its making pressure on piston which makes piston move up.
To solve this problem we must rely on the equations of the simple harmonic movement that define the period as a function of length and gravity as

Where
l = Length
g = Gravity
Re-arrange to find L,

Our values are given as


Replacing,



Therefore the height would be 25.348m
Psychoanalysis is a form of therapy that treats mental disorders through different ways, such as dream interpretation. It is a way of looking into the line between conscious and <span>unconsciousness </span>
Behaviorism is a theory that says that mental disorders are treated better with altering the persons behavior patterns.
I think they're different because behaviorism is just simply a theory and not actually a form of therapy.
Hopefully that helps you tell them apart!
