"Good thermal conductors are also good electrical conductors". If so, why dont't the conencting wire that are used to connect heaters get hot by conduction of heat from the heating element?
Can the potential difference between terminals of battery ever be opposite in the direction of emf?
Why does an electric bulb nearly burn out just as you turn on the light, almost never while the light is shining?
A cylindrical rod has resistance R. If we double its length and diameter, what is its resistance in terms of 'R'?
The critical angle for light in a certain substance is 45°. What is the polarizing angle?
Define respiration. Describe in detail the experiment to demonstrate the aerobic respiration with clean diagrams.
In which medium is the angle of polarization greater, rarer, or denser?
The beam of light after the reflection at a plane mirror, rotating 2000 times per minute, passes to a distant reflector. it returns to the rotating mirror from which it is reflected to make an angle of 1° with its original direction. If the distance between the mirror is 6250 m, calculate the velocity of the light.
Describe the T.S. of monocot stem with a well-labeled diagram and point out its differences with that of dicot stem.
