As we know that ,
Sublime is magnificent and great, base is anything low, ordinary, concise means short or compact, partial is not complete, and Insist is to make a request.
Therefore , required word is base . 

As per the meanings given below, the correct idiom will be ‘playing devil’s advocate’.
Take a rain check: postpone a plan.
Rain on someone’s parade: to spoil a moment.
Play devil’s advocate: to argue, just for the sake of it.
Play by the ear: to improvise.
Correct Sentence:
He was not agreeing to back off, as if he was playing devil’s advocate.
Hence, the correct answer is option C. 

Heparin is a form of Anticoagulant. Heparin is used to prevent blood clots from forming in people who have certain medical conditions or who are undergoing certain medical procedures that increase the chance that clots will form.

Various software enables us to accomplish many different tasks with computers. This software can be of various kinds ranging from freeware to proprietary to open source.

A Few Basic Categories of Softwares are:

1. Proprietary System Software:

• The term proprietary is derived from the Latin word ‘proprietas’ meaning property.
• It is a software which is limited in terms of its functionality.
• This kind of software is owned by an individual or a company (usually the one that developed it), so the rights are exclusively retained by them.
• However, these are licensed to end-users under certain specific terms and conditions.
• For example, the windows operating system where the windows source code is owned by Microsoft, Adobe Photoshop, Google Earth, Mac OS, etc.

1. Open-source Software: A software for which the human-readable source code is available for use, study, re-use, modification, enhancement, and redistribution by the users of that software. For example, Linux OS.
2. Public Domain Software: A software that is in the public domain, that is, the copyright has been explicitly given away by its owner and thus nobody owns it. Anybody is entitled to use such software for any purpose, including modifying it, giving it away and selling it in its original or modified form.
3. Freeware Software: It is a software that is available free of cost for use and distribution but which is copyrighted by its developer, who retains the rights to control its distribution, modify it and sell it in the future. It is typically distributed without its source code, thus preventing modification by its users. For example, Google Chrome, Adobe PDF Reader, Internet Explorer, etc.
4. Shareware: A software that is initially free and can be distributed to others as well, but needs to be paid for after a stipulated period. Once the stipulated period or the trial period is over and if the user wants to continue using the software after this trial period, they will be charged for it. For example, AntiVirus, WinZip, etc.

Hence, it can be concluded from the given points that Microsoft windows is an example of proprietary system software.

The correct answer is Bookmark.

• A Chrome Internet browser, a method of saving web page addresses for quick access is Bookmark.

Key Points

• Bookmark
  • “Bookmark” refers to links to sites that we store for easy access later.
  • A bookmark is a saved shortcut that directs your browser to a specific webpage.
  • It stores the title, URL, and favicon of the corresponding page.
  • Saving bookmarks allows you to easily access your favourite locations on the Web.

Additional Information

• Proxy Setting
  • ​A proxy server acts as a gateway between you and the internet.
  • It’s an intermediary server separating end users from the websites they browse.
• Clear Cache
  • When we use a browser it saves some information from websites in its cache and cookies.
  • Clearing them fixes certain problems, like loading or formatting issues on sites.
• Delete history
  • Windows short cut to delete history:
    • CTRL+SHIFT+DEL

Between 5 and 78:
First number = 6
Last number = 72

Hence, Option D is correct.

The starting four multiples of 2 is 2, 4, 6, 8
a=2 and d=2
n=4
S(n) = (n / 2) x [2a + (n - 1) x d]
S(4) = (4 / 2) x [2 x (2) + (4 - 1) x 2]
= (2) x [4 + 6]
= (2) x [10]
= 20

The coil has an inductance and resistance. We can visualize the coil therefore as an inductor and resistor in series. When we connect the DC battery across the coil, we have therefore and LR circuit. The steady state current is just i0 = V/R – same as above. So

An autotransformer used with a sodium vapour lamp should have high leakage reactance of windings.

Z_L = Z_in*
Z_L = 10 – j 50 = R_L + j × L
Current through c.v.t
I_max= 50 / (10+j50+j50)
=50/20Amp.
P_max = I²_maxRL
= (50/20)² x 10
= 62.5W

When switch was open. Both resistance are in series same current flow through R₁ and R_2. 
But when 'S' is closed resistance R3 parallel with R1 comes into operation.
where R₃>R₁, & now R₃ & R₁ are in parallel so that the effective Resistance Reff =(R₁||R₃).
Now the effective supply current will also increase since the total resistance of the circuit decreased.
so that the voltage across R₂ which is V₂ increases in turn V₁ is decreases to varify KVL.

Hence, the correct option is (B)

So, for first 33 kv, 5.2 metres and for next (220-33)= 187kv, 187/33=5.66 for which 5.66*0.3mt= 1.7 mt

In total 5.2+1.7= 6.9 metres for 220 kv

Hence, the correct option is c

Hence, the correct option is (A)

Angle between V and I i.e., θ will increase if X_L

Drawback of auto transformer
(1) If the transformer ratio K1 is far from unity, then the Auto transformer would not be economical one.
(2) The short circuit current in Auto transformer is higher than the short circuit current in two winding transformer.
(3) The main disadvantage of autotransformer is the direct electrical connection between low tension and high tension side, so it might be possible that the insulation of Cu may fail due to which a large current flow in windings.

E = 1V

Maximum dielectric stress/Minimum dielectric stress = D/d
