THOMSON'S ATOMIC MODEL:-
According to Thomson's atomic model positive charge is distributed uniformly over the entire body of the atom while the electrons are embedded in it. Similar to the seeds in a water melon.
Thomson's model failed to explain observed spectra emitted by an atom .
Q. How is radiation release from the body? Answer:- The body radiates energy by thermal conduction through the skin to the clothes, air, and so on around the body. A littl
Radioactive Decay Series The sequential decay of a given nucleus results in the production of a series of nuclei or elements. This series of elements thus formed is known as a
When is the combination of cells advantageous and why? (Mar 2009) What do you mean by internal resistance of a cell? Write down the value of internal resistance of an ideal cell
The maximum value of electric field in an electromagnetic wave is 800V/m. Determine the maximum value of magnetic intensity and the average value of pointing vector.
Q. Illustrate what is the dissimilarity between diffraction and interference? Answer:- Diffraction is the yielding of waves around an obstacle while interference is the me
What is Ancient view Ancient view: objects tend to stay if they are in motion; force is needed to keep something moving. This was a natural thing to believe in because we see
Is it possible to see your whole body in a flat, planar mirror that is LESS THAN half your height if the mirror is at an angle? (i.e. not parallel to your body)
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
Who discovered Proton? In 1886 Eugen Goldstein discovered canal rays (also called as anode rays) and showed that they were positively charged particles (ions) formed from gases
There are imaginary lines or path of the field in the given direction. The lines of force are assumed to make a closed path beginning from N pole and ending at S pole with no loss.
