Solution
An empty density bottle weighs 2 N. if it weighs 5 N when filled with water and 4 N when filled with olive oil, the relative density of olive oil is?
A
(1)/3
B
(2)/3
C
(1)/5
D
(2)/5
medium Difficulty
Verified Correct Answer: Option B
Physical Principles & Numerical Solution
relative density = (weight of substance )/weight of equal volume of water = (4 - 2)/5 - 2 = (2)/3

Solution
Given the progressive wave equation y = 5 sin (2000 \pit - 0.4x), calculate wave length
A
12.4 m
B
15.7 m
C
17.5 m
D
18.6 m
medium Difficulty
Verified Correct Answer: Option B
Physical Principles & Numerical Solution
Comparing y = 5sin (200 \pit - 0.4X) with the wave equation y = A sin (wt -KX) K = (2\pi)/\lambda = 0.4
∴ \lambda = (2\pi)/0.4 = 15.7M

The d.c generator has essentially the same components as the a.c generator except the presence of?
A
slip-ring
B
carbon brushes
C
split ring
D
armature
medium Difficulty
Verified Correct Answer: Option C
Physical Principles & Numerical Solution
A d.c. generator uses a split ring (commutator) to convert alternating current (a.c.) to direct current (d.c.), while an a.c. generator uses slip rings.

A
6 Ω
B
12 Ω
C
18 Ω
D
24 Ω
medium Difficulty
Verified Correct Answer: Option D
Physical Principles & Numerical Solution
The resistors are in series
∴ Reff = R1 + R2 + .....
= 4 + 4 + 4 + 4 + 4 + 4 = 24 Ω

Current Electricity & Electric Circuits
Solution
\(^{14}_7\)N + \(^4_2\)He → \(^{17}_8\)O + X
In the equation above, the particles X is?
A
a proton
B
a neutron
C
an α - particle
D
a β - particle
medium Difficulty
Verified Correct Answer: Option A
Physical Principles & Numerical Solution
for the conversion of mass 14 + 4 = 17 + x
∴ X = 18 - 17 = 1
for conservation pf charge:7 + 2 = 8 + y
y = 9 - 8 = 1
Thus, the element is 11X which is equal to hydrogen nucleus ( proton)

Attached Figure / Diagram
A
parallel to OX
B
parallel to OY
C
60o to OX
D
60v to OY
medium Difficulty
Verified Correct Answer: Option B
Physical Principles & Numerical Solution
Particles of the transmitting medium in transverse wave oscillate in a direction perpendicular to the propagation of the wave
Particle motion of a string (transverse wave) is parallel to OY (or perpendicular to OX)
