Q:

0 divided by 0

A) 0 B) 1
C) Undefined D) Indeterminate
 
Answer & Explanation Answer: D) Indeterminate

Explanation:

Indeterminate are those,which mathematics can’t determine.

Because we don’t actually know which one is the exact answer for this due to having lots of results for this.

Explanation::

      • Let us think by this analogy that,

0 / 1 = 0

0 / 2 = 0

…………

………..

we can say 0 / n = 0 from this we can write, 0/0 = 0

      • Again, another analogy,(from limiting concept of 1/0 = infinity)

1 / 0 = + or -

2 /0 = + or -

………

.…….

we can say 0 / 0 = 

      • Again, another analogy,

1 / 1 = 1

2/2 = 1

.……..

………..

we can say, 0/0 = 1

Now, you see it’s confusing. Every analog is mathematically correct then which one is the right answer for 0/0.  Therefore Mathematics can’t determine this fact.

So, 0/0 is indeterminate.

Q:

Which of the following chemical compounds has the highest boiling point?

A) Dimethyl ether (CH3OCH3) B) Methanol (CH3OH)
C) Methane (CH4) D) None
 
Answer & Explanation Answer: B) Methanol (CH3OH)

Explanation:

Chemical Compounds with stronger intermolecular forces have higher boiling points.

 

The order of strengths of intermolecular forces is:

 London dispersion < dipole-dipole < H-bonding

 

Methane (CH4) — London dispersion forces

Dimethyl ether (CH3OCH3) — dipole-dipole attractions

Methanol (CH3OH) — hydrogen bonding

Therefore, Methanol - CH3OH with H-Bonding have highest Boiling Point among the given chemical compounds.

A) Sukhoi-29 MKI B) Sukhoi-32 MKI
C) Sukhoi-31 MKI D) Sukhoi-30 MKI
 
Answer & Explanation Answer: D) Sukhoi-30 MKI

Explanation:

Brahmos, the world’s fastest supersonic cruise missile created history on today after it was successfully flight- tested for the first time from the IAF’s frontline fighter aircraft Sukhoi-30MKI against a sea-based target in the Bay of Bengal.


The armed forces are now capable of launching the Brahmos, which has a strike range of around 290 km and is described as the world’s fastest supersonic cruise missile, from land, sea and air, completing the tactical cruise missile triad for the country.
