Why wireless links provide lower reliability compared to wired links? You turn on your phone and after few seconds you can see a list of available 802.11 networks. From the 802.11 protocol point of view, how does this happens? Ethernet and 802.11 are both data-link layer protocols designed for wired and wireless networks, respectively. Why a 802.11 receiver expects ACK reception while Ethernet does not have such requirement. Where CSMA/CD and CSMA/CA are used? and what are the differences? What...

9. From top of an incline plane with height of 80.0 cm a cylinder with radius of 20.0 cm and mass of 5.0 kg is released. The cylinder is rolling down and reaches to end of the plane. The inclination angle of plane is 30 degrees. Find speed of cylinder at end of the plane. Plane is frictionless. Moment of inertia for ring is I= MR2. (use conservation of energy using rolling kinetic energy) 10. Find center of gravity...

Suppose a triangle is plotted on a coordinate plane with vertices located at ( -9, 3),(-3, -9) and (13, -1). What is the perimeter of the triangle?
Describe two group communication situations. What similarities and differences between the groups and their group communication situations. specifically discuss the type of group(s), group communication norms, of group communication interaction patterns.
9) A 2.00 kg box is launched up an inclined plane of angle 30 degrees with respect to the horizontal. The length of the inclined plane is 14.0 m. The coefficient of kinetic friction between the block and the inclined plane is u= 0.40. With what speed should the block be launched so that it just makes the top of the inclined plane? Work this problem using conservation of Energy. Hint: Conservation of Energy says that Wne+ ME, = ME,...
