The answer is D. Only student B is correct. Student A is incorrect because static electricity can be detected through the principle of electrostatic induction, which will indicate if there are static electricity on the surface of an object. A device which can detect static electricity is an electroscope. Moreover, for student B, it is correct that the cause for electric current to flow is the uniform flow of free electrons.

Anna11 [10]

Answer:

The program to this question as follows:

Program:

def isEvenPositiveInt(x): #defining method isEvenPositiveInt

   if x>0: #checking number is positive or not

       if x%2==0: #check true condition

           return True #return value True

       else:

           return False #return value False

   return False #return value False

print(isEvenPositiveInt(24)) #calling method and print return value

print(isEvenPositiveInt(-24)) #calling method and print return value

print(isEvenPositiveInt(23)) #calling method and print return value

Output:

True

False

False

Explanation:

In the above Python program, a method "isEvenPositiveInt" is defined, that accepts a variable "x" as its parameter, inside the method a conditional statement is used, which can be described as follows:

  • In the if block the condition "x>0" is passed, that check value is positive, if this condition is true, it will go to another if block.
  • In another, if block is defined, that checks the inserted value is even or not, if the value is even it will return "true", otherwise it will go to the else part, that returns "false".
