CSMA/CD Ethernet Collision Detection and LAN Access
CSMA/CD Collision Detection in Ethernet LANs
CSMA/CD (Carrier Sense Multiple Access/Collision Detection) is a media access control method that was widely used in early Ethernet technology and LANs when networks used a shared bus topology and each node (computers) was connected by coaxial cables. Today, Ethernet is typically full-duplex and the topology is either star (connected via a switch or router) or point-to-point (direct connection). Hence, CSMA/CD is not commonly used in modern switched, full‑duplex

Lysimeter Evapotranspiration (ET) Calculation
The Lysimeter method calculates Evapotranspiration (ET) based on mass change:
- Total Mass Change: (Initial Mass + Water Added) – (Final Mass + Water Lost) = 10 kg
- Daily Weight Change: 10 kg / 5 days = 2 kg/day
- Convert to Volume: 2 kg/day = 0.002 m³/day (Assuming 1 L = 1 kg and 1 L = 0.001 m³)
- Convert to Depth (m/d): 0.002 m³/day / Area of Bucket = 0.0002 m/day
- Convert to mm/d: 0.0002 m/day × 1000 = 0.2 mm/day

Sports Biomechanics: Levers, Rotation, Newton’s Laws
Third-Class Lever Example: Knee Extension
Q1: An example of a third-class lever is knee extension (like kicking a ball), where the force is between the fulcrum and load. The knee joint is the fulcrum (the pivot point where the lower leg rotates), the quadriceps tendon, inserting on the tibial tuberosity, provides the effort in the middle, and the leg and foot (plus any ball) form the load at the far end.
