Outline four advantages of digitalcameras over analogue cameras​

Computers and Technology
1 answer:
Phoenix [80]3 years ago
7 0

Answer:

Explanation:

A digital camera refers to a camera whereby the photographs are being captured in digital memory. An analogue camera refers to the traditional camera that typically sends video over cable.

The advantages of digital cameras over analogue cameras include:

1. Massive Storage Space:

There is a large storage space for photos and thus helps to prevent limitations to film. There are memory cards that can store several images.

2. Multiple functions:

The digital camera performs several functions like face detection, night and motion detection This makes capturing of images more fun and brings about better images.

3. Video Camera:

Digital cameras can also capture moving pictures while analog camera typically captures images that are still. Digital camera is vital as it can be used for live streaming.

4. Smaller and Lighter:

Digital cameras are usually smaller and lighter which makes them more portable and easy to carry about.

What would you have to know about the pivot columns in an augmented matrix in order to know that the linear system is consistent
Scrat [10]

Answer:

The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)

Then satisfying this theorem the system is consistent and has one single solution.

Explanation:

1) To answer that, you should have to know The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)

rank(A)

Then the system is consistent and has a unique solution.

<em>E.g.</em>

\left\{\begin{matrix}x-3y-2z=6 \\ 2x-4y-3z=8 \\ -3x+6y+8z=-5  \end{matrix}\right.

2) Writing it as Linear system

A=\begin{pmatrix}1 & -3 &-2 \\  2& -4 &-3 \\ -3 &6  &8 \end{pmatrix} B=\begin{pmatrix}6\\ 8\\ 5\end{pmatrix}

rank(A) =\left(\begin{matrix}7 & 0 & 0 \\0 & 7 & 0 \\0 & 0 & 7\end{matrix}\right)=3

3) The Rank (A) is 3 found through Gauss elimination

(A|B)=\begin{pmatrix}1 & -3 &-2  &6 \\  2& -4 &-3  &8 \\  -3&6  &8  &-5 \end{pmatrix}

rank(A|B)=\left(\begin{matrix}1 & -3 & -2 \\0 & 2 & 1 \\0 & 0 & \frac{7}{2}\end{matrix}\right)=3

4) The rank of (A|B) is also equal to 3, found through Gauss elimination:

So this linear system is consistent and has a unique solution.

What is a semiconductor
Elis [28]
A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave in the opposite way. I hope this helps and have a great day! (Also brainliest would be appreciated but you don’t have to) :)

____________________ is like a set of instructions that helps hardware process data into information.
Arte-miy333 [17]

Answer:

Program

Explanation:

Program is like a set of instructions that helps hardware process data into information.

Every hardware needs a program to process data into information.

For example take the example of a data processing software like MS Excel.

You open a spreadsheet and enter some data into your sheet. and then ask the program to do some calculations with this data and give you output results. The spreadsheet software does this processing in the background for you and provides you the results.

Without program a hardware doesn't know what to do with the data. Therefore, a program is like a instruction set that guides the hardware what to do with the data.

Note: The terms software and program are usually used together but there is a difference between software and program

A software is a generalized term and program is more like a specific term.

software can be made up of several different programs which performs many different tasks. On the other hand, a program only carry out a specific task or set of instructions.
