Relation between the zero and its coefficients.?

Nishita Dabas answered
For quadratic polynomial (ax2+bx+c)

sum of zeroes = -b/a

product of zeroes = c/a




and for cubic polynomial (ax3+bx2+cx+d )

sum of zeroes = -b/a

sum of product of zeroes taken at one time = c/a

product of zeroes = -d/a

If momentum is increased by 100% then the kinetic energy will be increased by .?

Vikram Khanna answered
Kinetic energy = p^2/2m    
If the momentum increases by 100% , then the p increases to 2p.

Substitute p =1
K before increase in momentum = p^2/2m = 1/2m                  - (1)
K' after increase in momentum by 100% = 2p^2/2m= 4/2m     - (2)

Let p = 1 
Divide (2) by (1) and substitute p=1
K'/K = (4/2m) / (1/2m)
            = 4 ( 2m gets divided by 2m to give 1)
      K'= 4K ( cross-multiplication)

Percentage increase = (K'-K / K) * 100
                                  = (4K-K/K) *100
                                  = (3K /K) *100
                                  = 3*100
                                 = 300%

When momentum of a body increases by 100% then its kinetic energy will increase by 300%.

What is vermiform appendix ?

Harsh answered
I think so......The appendix (or vermiform appendix; also cecal[or caecal] appendix; vermix; or vermiform process) is a blind-ended tube connected to the cecum, from which it develops in the embryo. The cecum is a pouchlike structure of the colon, located at the junction of the small and the large intestines.

Harsh answered
Fibrinogen is a glycoprotein that in Vertebrates circulates in the blood. During tissue and vascular injury it is converted enzymatically by thrombin to fibrinand subsequently to a fibrin-based blood cot.

Function of rRNA?

Ananya Sharma answered
Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.
