Which equation can be used to calculate the normal force on an object if you know the speed of the object, the coefficient of kinetic friction, and the force
of kinetic friction on the object?

it is easily magnetized.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .

snell's law

refractve index = sin incidence / sin refraction
