Computers and Technology
1 answer:
Semenov [28]3 years ago
4 0

Answer:

False

Explanation:

vector is like a dynamic array that has a special ability to resize automatically when it required.

vector has several functions:

like, insert() to insert the element in the vector.

delete() for delete the one element at a time.

empty() is also the function used in the vector. It is used for checking the vector is empty or not.

it gives the Boolean value (TRUE or FALSE), if the vector is empty it gives the output TRUE if the vector is not empty it gives the output FALSE.

It is not used for empty or deletes all elements of the vector.

Therefore, the answer is False.

Which technology can allow a single ground-based telescope to achieve images as sharp as those from the Hubble Space Telescope?
Ganezh [65]

Answer:

The correct answer to the following question will be "Adaptive Optics".

Explanation:

  • AO (Adaptive Optics) is a technique used to enhance optical system performance by reducing the impact of incoming gravitational wave distortions by compressing a mirror to compensate for the distortion.
  • It operates by calculating and compensating for defects in a wave-front with a system that corrects these errors as a deformable mirror or even a liquid crystal collection.
  • It is a technique that can make it possible for a single ground-based telescope to get images as clear as that of the Hubble Space Telescope.
  • Certain methods can achieve power resolution that exceeds the limit set by atmospheric distortion, for example, Aperture synthesis, Lucky imaging, and Speckle imaging.

Therefore, Adaptive Optics is the right answer.

16.50. Suppose we have a sequential (ordered) file of 100,000 records where each record is 240 bytes. Assume that B = 2,400 byte
Nat2105 [25]

Answer and Explanation:

Given that total number of records in a file = 100000

Each record consists of= 240 bytes

Given that B= 2400 bytes.

Then total blocks in file = 100000 records * 240 / 2400

= 10000 blocks.

Time that will take for exhaustive read

= s + r + b.btt

= 16 + 8.3 + (10000) * 0.8

= 8024.3 msec

Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.

Hence, X (s + r + btt) > 8024.3

X (16+8.3+0.8) > 8024.3

X > 8024.3/25.1

So that, X > 319.69

Hence, atleast 320 random reads should be made to search the file

Create a program that prints out a list of all the divisors of a number stored in a variable. (If you don’t know what a divisor
UkoKoshka [18]

Answer:

// Program is written in C++ Programming Language

// Comments are used for explanatory purpose

// Program starts here

#include<iostream>

using namespace std;

int main()

{

// Declare integer variable n which serves as the quotient.

int n;

// Prompt to enter any number

cout<<"Enter any integer number: ";

cin>>n;

// Check for divisors using the iteration below

for(int I = 1; I<= n; I++)

{

// Check if current digit is a valid divisor

if(n%I == 0)

{

// Print all divisors

cout<<I<<" ";

}

}

return 0;
