Solution:
Database integrity ensures that each row is uniquely identified by the primary key, which means that a proper search for an existing tuple (row) will always be successful.
Thus the required answer is D
Answer:
The correct option to the following question is option (B). e-business.
Explanation:
E-business is stands for the Electronic business.
E-business is the business which is conduct by the uses of the internet, Web, extranet or intranet, etc.
E-business is also known as the online business where online transactions take place.
E-business facilitates our customers that the selling and the buying of the goods between the consumers and the merchants.
If it’s computer files, that would be System Software and Application software.
“The System Software is the programs that allow the computer to function and access the functionality of the hardware. Systems software sole function is the control of the operation of the computer.
Applications software is the term used for programs that enable the user to achieve specific tasks such as create a document, use a database or produce a spreadsheet.”
Answer:
The complete Matlab code along with step by step explanation is provided below.
Matlab Code:
function Req=ParallelR(Number)
Number=input('Please enter the number of resistors: ');
if Number>10 | Number<=0
disp('Invalid input')
return
end
R=0;
for i=1:Number
r=input('Please enter the value of resistor: ');
R=R+1/r;
end
Req=1/R;
end
Explanation:
Parallel resistance is given by
First we get the input from the user for how many parallel resistors he want to calculate the resistance.
Then we check whether the user has entered correct number of resistors or not that is from 1 to 10 inclusive.
Then we run a for loop to get the resistance values of individual resistors.
Then we calculated the parallel resistance and keep on adding the resistance for N number of resistors.
Output:
Test 1:
Please enter the number of resistors: 3
Please enter the value of resistor: 10
Please enter the value of resistor: 20
Please enter the value of resistor: 30
ans = 60/11
Test 2:
Please enter the number of resistors: 11
Invalid input
Test 3:
Please enter the number of resistors: 0
Invalid input
These refer to the elementary steps of the scientific method.
The correct order is as follows:
- Keen observation of natural phenomena.
- The use of imagination and creativity to test understanding and predictions.
- An attempt to verify the understanding of observed natural occurrences establishing verifiable scientific knowledge
- Continued observance and testing to revise scientific knowledge.
- An understanding of how or why these natural phenomena occur.
