Key Points

There are many views to view a PowerPoint Presentation

Slide Sorter view:

• Slide Sorter view gives you a miniature picture of each slide.
• You can use this view to select and drag slides from one position to another within the slide show.
• The slide number appears near the bottom-right corner of each slide.
• To select a slide in Slide Sorter view, use the arrow keys to highlight the slide, or click on the slide you want to select.  A bold outline surrounds the selected Slide.
• You can select the slide in the Slide Sorter View and press the ‘Delete’ key to delete a slide.

Hence, The slide sorter view in a presentation is used for sorting out the position and view of different slides which can be done when those are displayed as thumbnails and can be sorted by moving.

Additional Information

Slide Show View

• The Slide Show view displays the slide full screen. When you use this view, the PowerPoint window is not visible and each slide occupies the complete screen area. 
• This view helps you to check the final sizes, colors, animation, transitions between slides, sounds, and other controls.
• To display the Slide Show view, select the Slide Show option from the View Menu.

Slide master:

• A slide master is a top slide in a hierarchy of slides that stores information about the theme and slide layouts of a presentation, including the background, color, fonts, effects, placeholder sizes, and positioning.
• To create a master slide: On the View tab, click Slide Master.

Notes Page:

• The Notes Page view enables you to view your speaker notes in a page view.
• Each slide created contains its own Notes Page.
• You can print these pages out to use as a reference while delivering the presentation.
• These notes do not show on the screen during Slide Show.

The correct answer is F11.

• The F11 key can take our screen into and out of full-screen mode quickly and easily. 

​Important Points

• Function key
  • A function key is a key on a computer or terminal keyboard which can be programmed so as to cause an operating system command interpreter to perform certain actions, a form of a soft key.

​ 

• F11​
  • The Most simple use is the F11 key can take our screen into and out of full-screen mode quickly and easily. 
  • F11 key can be used by combined with Shift, Ctrl, Alt keys.
    • Some of the uses of the F11 key in MS Word.
      • SHIFT + F11 = Go to the previous field.
      • CTRL + F11 = Lock a field.
      • CTRL + SHIFT + F11 = Unlock a field.
      • ALT + F11 = Display Microsoft Visual Basic Code.
      • ALT + SHIFT + F11 = Display Microsoft Visual Studio Code.

​Additional Information

• F8
  • ​​We can access the menu by turning on your computer and pressing the F8 key before Windows starts.

SMTP: simple mail transfer protocol is used for sending e-mail services between the servers.

FTP: It is an application layer protocol for file transfer

CONCEPT:

• Power: The rate of work done is called power.
  • It is denoted by P.
  • Mathematically it is written as

\(Power\;\left( P \right) = \frac{{\;W}}{{t}}\)

CALCULATION:

Given - mass of 1^st person (m₁) = 80 kg, mass of 2^nd person (m2) = 60 kg, time (t₁) = 12 sec, and time (t2) = 11 sec​

• The power to take an object to a certain height in 12 sec by 1^st person is 

\(\Rightarrow P_1 = \frac{mgh}{t}=\frac{80gh}{12}\)       ----(1)

• The power to take an object to a certain height in 11 sec by 2^nd person is 

\(\Rightarrow P_1 = \frac{mgh}{t}=\frac{60gh}{11}\)       ----(2)

On dividing equations 1 and 2, we get

\(\Rightarrow \frac{P_1}{P_2} =\frac{\frac{80gh}{12}}{\frac{60gh}{11}}=\frac{11}{9}\)

The mirror image of this image is:

Hence, option (2) is the correct answer.
