Study Notes
Thermodynamics
- When 20% of the heat supplied is used for increasing the volume by 1600 cm³ during a phase change, the internal energy increases.
Electromagnetism
- The intensity of magnetic induction at midpoint P can be determined due to the current as shown in the figure.
Photoelectric Effect
- A correct observation from the photoelectric effect experiment is implied.
Mechanics
- In a solid sphere of uniform density with a tunnel dug along its diameter, a particle released in the tunnel will experience a certain motion.
- If the distance between wires A and B is doubled and currents on them are doubled, the force F2 on 10 cm length of wire P will be affected.
- In a system with a hanging mass and a uniform rod, the tension in the cable AB is required to maintain equilibrium.
Simple Harmonic Motion
- If a particle is executing simple harmonic motion with a time period, the mass of the particle can be determined (given g = 10 ms–2).
Mechanics of Solids
- A 100 m long wire with a cross-sectional area of 6.25 × 10–4 m2 and Young’s modulus of 1010 Nm–2, when subjected to a load of 1250 N, will experience an elongation.
Thermodynamics
- If 1g of a liquid is converted to vapor at a pressure of 5 × 105 Pa, the specific latent heat of vaporization for the substance can be determined.
Electronics
- Photodiodes are preferably operated in reverse bias condition for light intensity measurement.
