Two circular glass microscope slides of diameter 1 cm are separated by a water film of thickness t = 10 mu m. The water completely wets the slides.
1. What is the contact angle of water on the slides?
2. What force is required to separate the glass slides?
In Figure 5-66, a force F of magnitude 7 N is applied to a FedEx box of mass m2 = 1.0 kg. The force is directed up a plane tilted by ? = 37°. The box is connected by a cord to a UPS box of mass 3.0 kg on the floor. The floor, plane, and pulley are fr..
