49how can it be???
i think we read something called excess pressure inside a liquid drop...isnt it?????????
1@subhomoy~~ATGS
yes excess pressure inside due to surface tension
1the answer for the given question may be A)RAY OPTICS: II)WAVE NATURE,B)PHOTOELECTRIC EFFECT:III)QUANTIZATION,C)BOHR MODEL: I)PARTICLE NATURE,D)A RADIOACTIVE MATERIAL:IV)EMIT ELECTROMAGNETIC WAVE
1Ray optics --> Particle nature
Photoelectric effect --> Quantization
Bohr Model --> Particle nature
Radioactive Material --> Emit electromagnetic wave, wave nature, particle nature, quantization
49A-I
B-I II
C-III II
D-IV
fully unsure...and most probably fully wrong..
11
a) I
B) I,III
C) I,III,IV
D) I,IV
2) PRESSIRE OUTSIDE IS MORE THAN PRESSURE INSIDE.....
NOW ANY1 EXP DA ANSWERS PLZ
1for the matrix match:
A)particle nature of light is considered in ray optics.
B)photoelectric effect verifies particle nature of light as wave nature cant explain it according to which the energy of light depends on intensity.
also quantisation of energy as energy is absorbed in quanta(E=hv)
C)Bohr's model was stsed taking the particle nature of electron,quantisation of angular momentum of electron in the stationary states where the moving electron didnt radiate energy(according to maxwell's electromagnetic law),and also emission of energy when an electron jumps from higher to lower energy level.
D)A radioactive substance emits electromagnetic waves(phenomenon of radioactivity)
dont know why they've given I for D,though,think it should be only IV
