Answer:
The acceleration is
Explanation:
From the question we are told that
The angle which the inclined plane make with horizontal is
The frictional coefficients are and
The force acting on the crate is mathematically represented as
Here f is the net force at which the crate is sliding down the plane which is mathematically represented as
is the force due to weight which is mathematically represented as
and the force due to friction which is mathematically represented as
So
substituting values
Answer:
The correct answer is option 'b': The rate of change of f changes from decreasing to increasing.
Explanation:
In differential calculus the behavior of any smooth function can be understood on the basis of slope of function alone. As slope of the function is the representation of rate of change of function.
Mathematically
Given as any function we have
1) if then the function is increasing
2) 1) if then the function is decreasing
3) 1) if then the function reaches a critical point.
Thus the nature of the function at any point is specified by the nature of the differential at the point provided the function is defined at that point at which we need to check the behavior.
Answer:
B. Zero
Explanation:
Here the number of downloads between minute 14 and minute 15 is 3000. The number does not increase or decrease so the slope is zero.
The slope of line between two points (x₁, y₁) and (x₂, y₂) is given by
Here,
The slope of a function is given by the differential of the function.
