completion of first second-> 2 new + 1 old =3
2nd second ->(3*2)6new +3 old =9
3rd second->(9*2)new + 9 old =27
4th second ->(27*2)new + 27 old=81
5th second ->(81*2)new + 81 old – 1(life time completes for 1st bacteria) =242
6th second ->242*2new + 242 old – 2(see born in first second which are new)=724
7th second->724*2new+724old – 6(see born in 2nd second which are new)=2166
8th second->2166*3 – 18 =6480
9th second=>6480*3 – 54 =19386
10th second=>19386*3 – 81*2 =57996

The stored procedure can be a program which is stored as well as ran within the DBMS (like, MySQL, Oracle, SQL Server). Stored procedures look like the Pascal program combined with a few SQL statements. Usually, they may be utilized to perform specific tasks which have to be executed as fast as possible, possibly since the program forms the overall performance bottleneck. Stored procedures could be known as through outside the actual database. Stored procedures work like functions within traditional programming languages.

in reply to: Define Binding energy #15518

Answer: When the masses of the constituent particles of a nucleus are added together, the sum is less than the nucleus itself. Binding energy is the mechanical energy required to disassemble a whole atomic nucleus into separate parts.

the mass of 1 person = 1.007825 amu
the mass of 1 neutron = 1.008665 amu
total = 2.016490 amu

The binding energy is the difference between the mass energy of the nucleus and its constituent particles. To separate the nucleus into a proton and neutron, energy equal to the binding energy must be added to the system.

Answer: Electrochemistry is a branch of chemistry that studies the changes that cause electrons to move and the movement of electrons is called electricity. Electricity can be generated in electrochemistry by movements of electrons from one element to another in a reaction known as a redox reaction or oxidation-reduction reaction.
A redox reaction involves a change in oxidation state of one or more elements. When a substance loses its electron then it is called oxidized and if it gains an electron then it is reduced. For example, for the redox reaction:
H2+F2→2HF
Rewrite it as
Oxidation: H2→2H++2e−
Reduction: F2+2e−→2F−
Overall Reaction: H2+F2→2H++2F−
In the above example H2 is being oxidized, while F2 is being reduced.

Answer: Python is an interpreter, interactive, object-oriented programming language which has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. The Python runs on many brands of UNIX, Amiga, on Windows, OS/2, Mac, and many other platforms. Python is also usable as an extension language for applications that need a programmable interface. The Python implementation is copyrighted but freely usable and distributable, even for commercial use.

Answer: Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is increasingly used for middleware applications to communicate between Server and clients. Java has features such as

• Portability
• Networking capabilities.
• Platform independence
• Manual memory allocation
• De allocation.
