Hydrogen Bomb

(a) Differentiate between nuclear fission and nuclear fusion. (b) Which of the two, nuclear fission and nuclear fusion, is made use of : (i) for the production of electricity ? (ii) for making a hydrogen bomb ? (c ) Which produces more energy : nuclear fusion or nuclear fission ? (d) Calculate the energy released in joules when 5 g of a material is completely converted into energy during a nuclear reaction. (e) How much is this energy in MeV ? (Speed of light = 3 xx 10^(8) m//s )

Hydroden bombs are based on

Who among the following wrote The Philosophy of the Bomb?

A bomb is released by a horizontal flying aeroplane. The trajectory of the bomb is

A bomb is dropped from an aeroplane flying horizontally with uniform speed. The path of the bomb of

A fighter jet plane is flying horizontally drops a bomb find the nature of path of bomb as seen by pilot.

A Bomber flying upward at an angle of 53^(@) with the vertical releases a bomb at an altitude of 800 m. The bomb strikes the ground 20 s after its release. Find : [Given sin 53^(@)=0.8, g=10 m//s^(2) ] (i) The velocity of the bomber at the time of release of the bomb. (ii) The maximum height attained by the bomb. (iii) The horizontal distance tranvelled by the bomb before it strikes the ground (iv) The velocity (magnitude & direction) of the bomb just when it strikes the ground.
