AIEEE Mock Test 3
Question:-
Option (A)
Monatomic
Option (B)
Diatomic
Option (C)
Diatomic
Option (D)
None of these
Correct Option:
B
Question Solution:
No. of moles = (5.6/22.4)=(1/4)
Heat in calories required to raise the temperature of 1 mole of the gas by 10°C is 12.5 x 4 = 50
Then Cv = (50/10) = 5
Cp = 5 + 2 = 7 calories
y = (Cp/Cv) =(7/5)= 1.4 (The gas is thus diatomic)
Question:-
Option (A)
750 W
Option (B)
500 W
Option (C)
250 W
Option (D)
1000 W
Correct Option:
C
Question:-
Option (A)
RCOR ; RCOOH
Option (B)
RCOR ; RCOR
Option (C)
RCOOH ; RCOR
Option (D)
RCOOH ; RCOOH
Correct Option:
B
Question:-
Option (A)
C = Æ
Option (B)
n(B) = n(C)
Option (C)
A=BÈC
Option (D)
n(B) = 2n(C)
Correct Option:
B
Question Solution:
C cannot be the empty set because, for instance
. We also have
So A ¹ B È C. In general, the determinant.
= a11a22a33 + a12a23a31 + a13a21a32 - a11a23a32 - a12a21a33 - a13a31a22
With the a’s being 0 or 1, equal 1 only if a11a22a33 = 1 and the remaining terms are zero; if a12a23a31 = 1 and the remaining terms are zero; or if a13a21a32 = 1 and the remaining terms are zero. Since there are three similar relations for determinants that equal -1. We must have n (B) = n(C).
Question:-
Option (A)
1.5 F
Option (B)
3 F
Option (C)
6 F
Option (D)
9 F
Correct Option:
D
Question Solution:
Fx = 1/2 mv2
F’ x = 1/2 m (3v)2
Hence v = |m|
(F’/F) = 9
Question:-
Option (A)
0 J
Option (B)
2pJ
Option (C)
4pJ
Option (D)
6pJ
Correct Option:
D
Question Solution:
w = - ΔU = Ui - Uf
Ui = `P. `B = NiAB
Uf = - Ni AB
W = 2Ni AB = 2 x 100 x 1 x p x 10 x 10 x 10-4 x 3 = 6pJ
