A Foucault pendulum consists of a brass sphere with a diameter of 35.0 cm suspended from a steel cable 10.5 m long (both measurements made at 20oC). The swinging sphere clears the floor by a distance of only 2 mm when the temperature is 20oC. At what temperature will the sphere begin to brush the floor

radiation warms things up temp rises convection currents air circ windy weather

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

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 .
