2. In a LAN, the physical address, also known as the MAC (Media Access Control) address, is used to transfer frames to appropriate destination.
4. Compound pendulums have several applications, including:

• Timekeeping devices: pendulum clocks and watches use a pendulum to keep time with great accuracy.
• Seismology: a compound pendulum can be used to measure the acceleration due to gravity, which is important in the study of earthquakes and other seismic activity.
• Aircraft design: the behavior of a pendulum in flight can be used to study the stability and control of aircraft.
• Physics education: the compound pendulum is often used in physics demonstrations and experiments to illustrate concepts such as simple harmonic motion and moments of inertia.
