Question

1. A cylinder and pulley have radii Rc = 0.150 m and Rp = 0.120 m, respectively. Consider these two rotating objects to be uniform solid cylinders (i.e. disks) with masses Mc = 5.00 kg and Mp = 2.00 kg, respectively. The cylinder and pulley turn without friction about their stationary axles that pass through their centers. A light rope is wrapped around the cylinder. One side of the rope passes over the pulley and has a 4.00 kg uniform rectangular block suspended from its free right end. The other side has a 2.00 kg uniform rectangular -shaped load suspended from the rope

Explanation / Answer

Here's a good and somewhat surprising example: Radio waves cannot be heard! Their frequencies are so high that our hears cannot detect them. This is why we must have the help of electronics that *can* hear them, and transform them a little so we can hear their 'signals'. Hope this helps you.
