Meghna Thapar 5 years, 7 months ago

Bioinformatics has become an important part of many areas of biology. ... It plays a role in the text mining of biological literature and the development of biological and gene ontologies to organize and query biological data. It also plays a role in the analysis of gene and protein expression and regulation. Biological databases play a central role in bioinformatics. They offer scientists the opportunity to access a wide variety of biologically relevant data, including the ge- nomic sequences of an increasingly broad range of organisms.

Sia ? 6 years, 7 months ago

For a.c. voltage
{tex}V = {V_0}\;\sin \left( {\omega t - \phi } \right){/tex}
The peak value
{tex}{V_0} = 220\sqrt 2 = 311V{/tex}
The rms value of voltage
{tex}{V_{rms}} = \frac{{{V_0}}}{{\sqrt 2 }};\;{V_{rms}} = 220V{/tex}
Average voltage in full cycle is zero. Average voltage in half cycle is
{tex}{V_{av}} = \frac{2}{\pi }{V_0} = \frac{2}{\pi } \times 311 = 198.17V{/tex} = 198.17 V
As {tex}\omega = 2\pi f,\;2\pi f = 314{/tex}
i.e. {tex}f = \frac{{314}}{{2 \times \pi }} = 50\;Hz{/tex} = 50 Hz

ANSWER

Sir, This is a question regarding sequence. Q. As we know a sequence is a function whose domain is the set of natural numbers. Suppose we write the numbers 1,25,5,16,8,49,29,14, ...(taken arbitrarily) as marks obtained by students roll number wise(1,2,3,4...). Then we can define a funtion f from the set of natural numbers to R the set of real numbers such that f(n) is the marks of nth student. Then can we say that the numbers 1,25,5,16,8,49,29,14...is a sequence?
