high energy physics and nuclear physics

. Important component of Co-A required for oxidative metabolism. Dermatitis, graying of hairs, retarded body and mental growth, reproductive debility. 6. Vit. H (Biotin) (C10H16N2O3S) Yeast, vegetables, fruits, wheat chocolate, eggs, groundnut; synthesized by intestinal bacteria. Essential for lipi..

! The tremendous quantities of energy available in the atomic bomb and the hydrogen bomb stem from the large value of the constant c 2 in Einsteins equation. Conversion of a tiny portion of matter yields a huge quantity of energy. Nuclear plants also rely on this type of en..

Nitrogen has atomic radius 0.70 A and ionic radius 1.71 A. It has a triple bond having bond length 1.09 A. Because of its high dissociation energy (bond enthalpy) of 945 KJ/mol, it is very stable. When electric spark is passed through nitrogen gas at low pressure, yellow ..

1. Nature : Diamond is the purest form of carbon and the hardest known substance. It is transparent, lustrous and may be coloured due to the presence of impurities. For example, black diamonds, called carbonado, contain traces of graphite. The abrasive nature or hardness of diamond is due to its..

Natural sources of radiations to which humans are exposed such as ultraviolet rays from the sun, cosmic rays from space and emissions from naturally occuring radioactive elements cause skin cancer. Medical, industrial and military activities have created additional sources of high ..

) proceeds in backward direction (2) proceeds in forward direction (3) proceeds in both directions to attain equilibrium (4) no reaction will proceed 42. The value of which of the following functions generally tends to maximum in a spontaneous reaction? (1) enthalpy (2) free energy (3) in..

. For instance, if density of nucleus is measured using electron-nucleus collision, the distance at which density of nucleus becomes 50 % is considered the average radius of the nucleus. On the other hand when the radius is determined from the collision of 01-particles with the nucleus, it is calle..

Diethyl ether is a colourless, pleasant odoured, highly volatile liquid. It boils at 307.5K. It is highly inflammable. The boiling point of C2H5 - O - C2H5 is much lower than that of alcohol containing the same number of carbon atoms, C4H9OH, as ether cannot associate its mole..

1. Non metals are brittle and cannot be used to make sheets or wires. 2. Non metals are bad conductors of heat and electricity except graphite. 3. Most of the solid non-metals are quite soft except diamond. 4. Non metals can be easily broken, i. e the tensile strength of non metals is low. 5. ..

Acetic acid is a colourless pungent odoured corrosive liquid. It boils at 118C. It is miscible in all proportions with water, ether and ethylalcohol. The high boiling point of acetic acid compared to the alkane, alkyl halide, ether and alcohol of same molecular weight is attributed to s..
