Study Notes
Heat Transfer
- Conduction is the method of heat transfer involved when the wax pieces begin to fall one by one after a flame is brought in contact with the rod.
Fluid Pressure
- Pressure at points B and C are equal since they are at the same horizontal level.
- Pressure at point D (bottom of the container) is greater than at points B and C due to the weight of the water.
- Pressure at point A (surface of the water) is atmospheric pressure.
Sound Waves
- Rita's voice can be heard by Raj and his friends through the string-telephone, as sound waves are transmitted through the string.
