IMPULSE

IMPULSE
            When a large force acts upon a body for a very short interval of time and for this interval the product F x ∆t  is called impulse. Thus product of force and time for which force acts is called impulse of the force. Impulse =F x ∆t Impulse is a vector quantity, having same direction as that of force
Explanation:Consider Force acts upon a body and changes its momentum from 
in a short interval of time ∆t, the We can write:-
Units:
            The unit of impulse is Ns and its dimension is same as that of momentum.

Deoxyribonucleic acid (DNA)

Deoxyribonucleic acid (DNA) DNA is heredity material. It controls the properties and potential activities of a cell. Location in cell DNA occurs in chromosomes, in the nuclei of the cells and in much lesser amounts in mitochondria and chloroplast. Chemical composition of DNA DNA is made of four kinds of  nucleotides; d-adenosine monophosphate (d-AMP) d-guanosine monophosphate (d-GMP) d-cytidine monophosphate (d-CMP) d-thymidine monophosphate (d-TMP) These nucleotides are united with one another through phosphodiester linkages in a specific sequence to form long chains. Two nucleotides join to form  dinucleotide  e.g nicotinamide adenine dinucleotide  (NAD) which is important coenzyme in several oxidation-reduction reactions in the cell. Three nucleotides join to form  trinucleotide . Ratio of Bases in DNA In 1951,  Erwin Chargaff  provided data about the ratios of different bases present in DNA. This data suggested that ade...

Mr chips important short questions.

Chapter#1 Question # 1:How does a person spend his time in old age after retirement? Answer : After retirement when a person becomes old, he has nothing to do.

Question # 4:What did Chips do before going to the bed? Answer : Chips was spending a pleasant and placid time at Mrs. Wickets after his retirem...

What are zymogens? How they are formed? What Is a Zymogen?   A zymogen is like a wrapped candy bar. In order to get to the good stuff, you need to tear away what's keeping you from it.  Zymogens , or  proenzymes , are enzymes that aren't functioning yet because their action is infertile by a 'wrapper'. The 'wrapper' can be a link between two  amino acids  (the building blocks of proteins), like a piece of string keeping a box closed. Or it can be an further section of protein, like a jar lid. How they are formed? When cells make enzymes, especially proteases, they often make them as zymogen, an inactive form of the enzyme. This is so they don't go crazy and are only used when needed. Imagine your reaction if your blender suddenly hopped about on the counter, out of control, spewing half-chopped fruit everywhere. The counter would be a mess, and so would the cell. You can recognize most zymogens by their name. Enzymes that begin with ...
