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 .
YES GRAVITY CAN BAND LIGHT e.g. GRAVITY OF BACK HOLE IS VERY STRONG
Potential barrier One either side of the junction, the region ‘D' becomes free from mobile charge carriers. That is on n-type side of D, no free electrons exist and on p-type s
why The magnitude of known potential difference must be greater than the value of unknown potential difference to be measured.
Explain Friction Force (Ffrict) Force exerted by a surface as an object moves across it or makes an effort to move across it. There are 2 parts of friction force - sliding and
Advantages of three phase system over single phase system a) Rotating magnetic field can be set up, by passing three-phase current by stationary coils. b) Polyphase s
Why do magnetic field lines contract longitudinally and exert a lateral pressure?
In this system, d = 6 in., D = 12 in., Δz 1 = 6 ft, and Δz 2 = 12 ft. The discharge of water in the system is 10 cfs. Is the machine a pump or a turbine? What are the pressures a
A positively-charged subdivision is moving southward in a downward-directed uniform magnetic field. The magnetic force is the merely force if any acting on the particle. Throughout
Five people are playing tug-of-war. Anders and Alyson pull to the right with 45 N and 35 N, respectively. Calid and Marisol pull to the left with 53 N and 38 N, respectively.
