Question Discussion & Solution

PowerPoint is a presentation program developed by Microsoft that creates a slide show of important information, charts, and images for a presentation. 

Key Points Five different ways to view PowerPoint presentations:

1. Slide View shows one slide at a time Slide view is optimized for editing.
2. Outline View shows the contents of your presentation in outline format.
   • This view is optimized for organizing and arranging the content of your presentation.
3. Notes Page View shows one slide at a time with the speaker's notes.
   • This view is best to review the notes for slides.
4. Slide Show View shows your presentation as it will look to the audience.
   • This view displays one slide at a time in full-screen mode.
5. Slide Sorter View shows a thumbnail image of each slide in the presentation.
   • This view is best when you want to rearrange the order of the slides

Each view is optimized for a specific purpose. 

Therefore, inline is not a Microsoft PowerPoint view.

LAN :

• LAN stands for Local Area Network.
• It's a group of computers which belong to the same organisation, and are linked within a small geographic area using a network using the same technology (Ethernet).
• E.g. Wi-Fi

MAN :

• MANs (Metropolitan Area Networks) connect multiple geographically nearby LANs to one another at high speeds.
• A MAN lets two remote nodes communicate as if they were part of the same local area network.
• E.g. microwave antenna on a TV news van, extended high in the air, beaming video and sound back to the main TV studio.

WAN:

• A WAN (Wide Area Network or extended network) connects multiple LANs to one another over great geographic distances.
• WANs operate using routers, which can "choose" the most appropriate path for data to take to reach a network node.
• E.g.: Internet

PAN:

• A personal area network (PAN) is a network used for data transmission amongst devices such as computers, telephones, tablets, personal digital assistants, fax machines and printers, that are located close to a single user

E.g. Bluetooth

The correct answer is Vitamin A.

• Vitamin A causes Night Blindness.

Key Points

• Night blindness is a type of vision impairment also known as nyctalopia. People with night blindness experience poor vision at night.
• Vitamin was first invented by FG Hopkins.  However, the term vitamin was coined by C Funk. 
• Good sources of vitamin A include cheese, eggs oily fish.

Additional Information

• Vitamin B₁₂ deficiency may lead to a reduction in healthy red blood cells (anaemia). 
• Vitamin C is found in citrus fruits and vegetables.
  • Scurvy results from a deficiency of vitamin C in the diet.
• The signs and symptoms of vitamin D deficiency include Fatigue, Bone pain, muscle weakness, muscle aches, or muscle cramps.
  • Rickets is caused due to deficiency of vitamin D
• Vitamin E deficiency can cause nerve and muscle damage loss of body movement control, muscle weakness, and vision problems.

Explanation:

• Sound is a longitudinal mechanical wave that propagates by making compressions (high pressure) and rarefactions(low pressure) in its propagating medium. 

• The amplitude of wavelength is the maximum distance the particle oscillating moves from the mean position.
• The frequency of the wave is the number of times one complete cycle of compressions 

• More the frequency more is the pitch of the sound, the sound is having more shrillness. 
• The more the amplitude the more is the loudness of the sound. 

So, loudness depends upon the amplitude.

Important Points 

• The Pitch of the sound depends upon frequency. 
• Mathematically, loudness is directly proportional to the square of the amplitude.

Feminine means qualities or appearance of aFemale.

Similarly,

Masculine means qualities or appearance of a Male.
