6 Questions
State and prove the law of conservation of angular momentum.
The total angular momentum of a system remains constant if no external torque is applied. This can be proven using the principle of the conservation of angular momentum.
What is capillarity? State any two uses of capillarity.
Capillarity is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. Two uses of capillarity are in wicking action in plants and the function of capillary tubes in medical devices.
Define linear SHM and show that SHM is the projection of UCM on any diameter.
Linear Simple Harmonic Motion (SHM) is a type of periodic motion where the restoring force is directly proportional to the displacement. The projection of Uniform Circular Motion (UCM) on any diameter results in SHM.
Differentiate between harmonics and overtones (two points).
Harmonics are whole number multiples of the fundamental frequency, while overtones are any frequency higher than the fundamental frequency. Harmonics are integer multiples, while overtones are any additional frequencies present.
Draw a neat labelled diagram of the internal structure of a galvanometer.
A galvanometer consists of a coil suspended between the poles of a permanent magnet, a spring for restoring force, a pointer, and electrical connections.
Define magnetization and magnetic intensity.
Magnetization is the process of making a material magnetic, while magnetic intensity is the magnetic field strength within a material.
Test your knowledge with questions about capacitor capacity, resistance of an ideal voltmeter, behavior of ferromagnetic substances, and logic gates. Also includes questions on angular momentum and conservation laws.
