For network shown in figure, determine V0 and ID. (Where, ID = Current flowing in the diodes)

Detailed Solution: Question 2

Direction of current ID is the same direction as arrow in the diode symbol. Therefore, both the diodes are in forward Bias; hence voltage drops across their terminals are VSi and VGe are 0.7 V and 0.3 V respectively.

E = 12 V > (0.7 V + 0.3 V).

An iron wire AB of length 3 m at 0°C is stretched between the opposite walls of a brass casing at 0°C0°C as shown in the figure below. The diameter of the wire is m0.6 mm. What extra tension will be set up in the wire when the temperature of the system is raised to 40°C?

Given αbrass = 18 × 10−6 K−1, αiron= 12 × 10−6 K−1, Yiron = 21 × 1010 N m−2

Detailed Solution: Question 4

Increase in length of the iron wire = LαΔt = L × 12 × 10−6 × 40 = 48L × 10−5 m

Increase in length of the brass tube = LαΔt = L × 18 × 10−6 × 40 = 72L × 10−5 m

Since the increase in length of the brass tube is greater than that of the iron wire, the latter will be tightened. Let T be the tension in the wire. Then,

T = 21 × 1010 × 24 × 10−5 × 9π × 10−8 = 14.2 N

The highest industrial consumption of molecular hydrogen is to produce compounds of element:

Detailed Solution: Question 8

Hydrogen combines with nitrogen to produce ammonia in Haber's process.
N2(g) + 3H2(g) ⇌ 2NH3(g)
In this process, iron oxide is used with small amounts of K2O and Al2O3 to increase the rate of attainment of equilibrium.
Optimum conditions for the production of ammonia are a pressure of 200 atm and a temperature of 700 K.
Earlier, iron was used as a catalyst with molybdenum as a promoter in this reaction.

Detailed Solution: Question 9

  • ClO3- : A very reactive inorganic anion.
  • The term chlorate can also be used to describe any compound containing the chlorate ion, normally chlorate salts. 
  • Example: Potassium chlorate, KClO3

Which of the following chemical reactions represents Hall-Heroult Process?

MET Mock Test - 9 - Question 11
Save

The correct order of electron gain enthalpies of Cl, F, Te and Po is

Detailed Solution: Question 11

Te → -190 kJ mol-1
Po → -174 kJ mol-1
F → -333 kJ mol-1
Cl → -349 kJ mol-1
Chlorine has the highest electron gain enthalpy, even greater than F, due to small size and repulsion in fluorine atom. Down the group, electron gain enthalpy decreases and along the period it increases.
So, the correct order is Po < Te < F < Cl.

Metals generally melt at very high temperature. Amongst the following, the metal with the highest melting point will be

Detailed Solution: Question 12

Melting points of the given metals:
Hg: -38.83°C
Ag: 961.8°C
Ga: 29.76°C
Cs: 28.44°C
So, the metal having the highest melting point is Ag.

PCl5 is well known but NCl5 is not because

Detailed Solution: Question 14

PCl5 is well known but NCl5 is not because nitrogen does not have vacant d-orbitals in its valence shell. So, nitrogen cannot expand its octet. On the other hand, phosphorus has vacant d-orbitals in its valence shell which enables it to expand its octet.

The mean and the standard deviation (s.d.) of 10 observations are 20 and 2, respectively. Each of these 10 observations is multiplied by p and then reduced by q, where p ≠ 0 and q ≠ 0. If the new mean and new s.d. become half of their original values, then q is equal to

Detailed Solution: Question 19

μ = 20, σ2 = 2
And pμ - q =  20/2 ⇒ 20p - q = 10
Also,
|p| σ2 = |p| × 2 = 1 ⇒ 
If p = 1/2 ⇒  q = 0 (rejected)

The number of choices for  such that (p Δ q) ⇒ ((p Δ ~q) v ((~p) Δ q)) is a tautology, is

Detailed Solution: Question 20

Let x : (p Δ q) ⇒ (p Δ ~q) v (~p Δ q)
Case-I
When Δ is same as v, then (p Δ ~q) v (~p Δ q) becomes (p v ~q) v (~p v q) which is always true. So, x becomes a tautology.
Case-II
When Δ is same as ∧, then (p ∧ q) ⇒ (p ∧ ~q) ∨ (~p ∨ q).
If p ∧ q is T, then (p ∧ ~q) ∨ (~ p ∧ q) is F.
So, x cannot be a tautology.
Case-III
When Δ is same as ⇒ , then (p ⇒ ~q) v (~p ⇒ q) is same as (~p v ~q) v (p v q), which is always true. So, x becomes a tautology.
Case-IV
When Δ is same as ⇔, then (p ⇔ q) ⇒ (p ⇔ ~q) v (~p ⇔ q).
p ⇔ q is true when p and q have same truth values, then p ⇔ ~q and ~p ⇔ q are both false.
Hence, x cannot be a tautology.
So, finally, x can be v or ⇒.

The number of values of x in the interval  for which 14cosec2x - 2sin2x = 21 - 4cos2x holds, is _________


Detailed Solution: Question 25


14cosec2 x - 2sin2 x = 21 - 4cos2 x
= 21 - 4(1 - sin2 x)
= 17 + 4sin2 x
14cosec2 x - 6sin2 x = 17
Let sin2x = p
14/p- 6p = 17
⇒ 14 - 6p2 = 17p
6p2 + 17p - 14 = 0
p = -3.5, 2/3
⇒ sin2x = 2/3
⇒ sin x = 

∴ There are total 4 solutions.
