Answer:
C. Wait for about 30 minutes for the system to cool downand try again.
Explanation:
In computer system troubleshooting, there are two areas where problems can arise. They are hardware and software related issues.
software issues are application related like an application not installed properly, malicious software attack, corrupted operating system etc, while hardware has to do with a faulty hardware component in the system.
Example of a hardware related issue, when the active fan is faulty, the computer overheat and eventually shuts down to cool the system. When it cools down, the computer can boot again.
To confirm that the fan is faulty, when it shuts down to cool, wait for some time and try booting the system again. If it comes on, then the fan is bad.
Answer:
In artificial intelligence, an expert system is a computer system emulating the decision-making ability of a human expert.[1] Expert systems are designed to solve complex problems by reasoning through bodies of knowledge, represented mainly as if–then rules rather than through conventional procedural code.[2] The first expert systems were created in the 1970s and then proliferated in the 1980s.[3] Expert systems were among the first truly successful forms of artificial intelligence (AI) software.[4][5][6][7][8] An expert system is divided into two subsystems: the inference engine and the knowledge base. The knowledge base represents facts and rules. The inference engine applies the rules to the known facts to deduce new facts. Inference engines can also include explanation and debugging abilities.

#library
import math
#read the radius of sphere
rad=float(input("Enter the radius of sphere:"))
# find the Surface area
A=4*math.pi*rad**2
V=(4/3)*math.pi*rad**3
#print the Surface area
print("The surface area of the sphere is:",A)
#print the Volume of sphere
print("The volume of the sphere is:",V)
Explanation:
Import math library to use the value of "pi".Read the radius of sphere from user and assign it to variable "rad".Then calculate the surface area A = 4*3.14r**2 and volume of sphere V=V = 4/3 x 3.14r**3.Print the surface area and volume of the sphere.
Output:
Enter the radius of sphere:2.5
Surface area is: 78.539812
Volume of sphere is: 65.44985
The cross join is the type of join that is used to create the query.
<h3>What is a join statement?</h3>
This is the term that is used in database programming in order to refer to the select statement that helps in the combination of the records that are contained in two different tables.
The condition that this is used to make happen is what is called the Join statement. There are different types of this type of condition. They are:
A: Explicit inner join
B: Implicit inner join
C: Outer join
D: Cross join

Recursive functions are functions that are called from within itself
The recursive function DigitCount() in Python where comments are used to explain each line is as follows:
#This defines the function
def countDigits(n):
#If the integer is <em>less than 10</em>
if n< 10:
#Then the integer has <em>1 digit</em>
return 1
#Otherwise,
else:
#Count the number of integers
return 1 + countDigits(n / 10)
At the end of the function, the count of integers is returned to the main function
