Answer:

Reflection

Explanation:

Reflection is the property of light in which when a ray of light hits a smooth surface, it bounces back in the direction in which it came from. If i is the angle between the normal to the surface and the incident ray, and r is the angle between the normal and reflected ray, the law of reflection states that the angle of incidence equals the angle of reflection. That is, i = r.

So, to record the image of an object with a camera, one property of light that makes that possible is reflection because, the incidence rays form an image of the object in the camera, while the reflected rays reflect the image so that it is visible to the eye.

Write a program that will ask the user for a set of ten numbers. After all ten numbers have been entered, the program will displ

muminat

Answer:

In Python:

nums = []

larg= []

small = []

while True:

for i in range(10):

num = int(input(": "))

nums.append(num)

print("Smallest: "+str(min(nums))); print("Largest: "+str(max(nums)))

larg.append(max(nums))

small.append(min(nums))

another = int(input("Press 1 to for another sets: "))

nums.clear()

if not another == 1:

break

print("Average Large: "+str(sum(larg)/len(larg)))

print("Average Small: "+str(sum(small)/len(small)))

Explanation:

This initializes the list of input numbers

nums = []

This initializes the list of largest number of each input set

larg= []

This initializes the list of smallest number of each input set

small = []

This loop is repeated until, it is exited by the user

while True:

The following iteration is repeated 10 times

for i in range(10):

Prompt the user for input

num = int(input(": "))

Add input to list

nums.append(num)

Check and print the smallest using min; Check and print the largest using max;

print("Smallest: "+str(min(nums))); print("Largest: "+str(max(nums)))

Append the largest to larg list

larg.append(max(nums))

Append the smallest to small list

small.append(min(nums))

Prompt the user to enter another set of inputs

another = int(input("Press 1 to for another sets: "))

Clear the input list

nums.clear()

If user inputs anything other than 1, the loop is exited

if not another == 1:

break

Calculate and print the average of the set of large numbers using sum and len

print("Average Large: "+str(sum(larg)/len(larg)))

Calculate and print the average of the set of smallest numbers using sum and len

print("Average Small: "+str(sum(small)/len(small)))

The listing of a directory shows certain files with permissions set to rwsr-xr-x. what does this indicate?

marta [7]

"rws" means that the user has permissions to read, write and setuid. "r" means the user can read the file and "w" means that the user can write to the file. "s" stands for "setuid" (set user id) is a permission bit that allows the users to execute a program with the permissions of its owner. The "s" can also mean "setgid" (set group id) is a bit that allows the user to execute a program with the permissions of the group owner.

Assume the method doSomething has been defined as follows: public static void doSomething (int[] values, int p1, int p2) { int t

Dmitriy789 [7]

Answer:

The answer to this question is option "b".

Explanation:

In the method definition, we perform swapping. To perform swapping we define a variable "temp" that swap values of variable p1 and p2 and store in array that is "values". and other options are not correct that can be defined as:

In option a, It does not insert any new value in array because we do not pass any value in function.
In option c, The function does not copy and assign a value in a new array because in this function we not assign any new array.
In option d, It is incorrect because it can not move an element into high index position.

A hidden backlog contains the projects that the IT department is not aware of because of low feasibility.

Finger [1]

Answer: True

Explanation:

Yes, the given statement is true that the due to the very low feasibility the IT (Information technology) department are not aware of the hidden backlog that basically contain projects.

The feasibility is the main factor in the IT department as it helps to study whole objective of the project and then also uncover all the strength and weakness of the project so that we can easily go through the details to make the project more efficient and reliable.

The purpose of this assignment is to determine a set of test cases knowing only the functionâ€™s specifications, reported hereaf

Nesterboy [21]

Answer:

The program is written using PYTHON SCRIPT below;

N=int(input(" Enter number of Rows you want:"))

M=[] # this for storing the matrix

for i in range(N):

l=list(map(int,input("Enter the "+str(i+1)+" Row :").split()))

M.append(l)

print("The 2D Matrix is:\n")

for i in range(N):

print(end="\t")

print(M[i])

W=[] # to store the first non zero elemnt index

T=[] # to store that value is positive or negative

L=len(M[0])

for i in range(N):

for j in range(L):

if (M[i][j]==0):

continue

else:

W.append(j) # If the value is non zero append that postion to position list(W)

if(M[i][j]>0): #For checking it is positive or negative

T.append(+1)

else:

T.append(-1)

break

print()

print("The first Non Zero element List [W] : ",end="")

print(W)

print("Positive or Negative List [T] : ",end="")

print(T)

Explanation:

In order for the program to determine a set of test cases it takes in input of 2D matrix in an N numbet of rows.

It goes ahead to program and find the column index of the first non-zero value for each row in the matrix A, and also determines if that non-zero value is positive or negative. The If - Else conditions are met accordingly in running the program.
