5. a certain bolt is held in place by a torque of 13 n-m.
if you have a 0.2 m long wrench, as shown, and apply a
force of 60 n, will that be enough to cause the bolt to
rotate? show your work!

6.
how much torque will 75 n produce if the wrench
shown is 0.3 m long?

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?
