Acutting tool under microprocessor control has several forces acting on it. one force is , a force in the negative y-direction whose magnitude depends on the position of the tool. the constant is α = 2.50 n/m³. consider the displacement of the tool from the origin to the point x= 3.05 m , y= 3.05 m . calculate the work done on the tool by if this displacement is along the straight line y = x that connects these two points.

Porque crees que el agua no podia subir mas de 10 m de altura con ese tipo de bomba

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?
