A cork floats in water while an iron nail sinks. Which statement explains the nail sinking?
RRB Group-D
12/10/2018 / Shift III
2018
✓ Answer:BThe iron nail is denser than water
Iron's density exceeds water's, while cork's average density is less than water's.
52
The floating of an object on water is explained by:
RRB NTPC (Stage-I)
27/04/2016 / Shift II
2016
✓ Answer:CArchimedes' principle
A floating object displaces fluid whose weight equals its own weight.
53
Pressure applied to a confined liquid is transmitted:
RRB Technicians Grade-III
27/12/2024 / Shift I
2024
✓ Answer:AUndiminished in all directions
Pascal's law states that an applied pressure change is transmitted undiminished throughout a confined fluid.
54
A body partly or wholly immersed in a fluid experiences an upward force equal to the weight of displaced fluid. This is:
RRB JE; RRB Group-D
14/12/2014 / Red Paper; 15/10/2018 / Shift I
2014; 2018
✓ Answer:BArchimedes' principle
This is the statement of Archimedes' principle.
55
One atmosphere is approximately equal to:
RRB Technicians Grade-III
23/12/2024 / Shift II
2024
✓ Answer:D1.01 × 10⁵ Pa
One standard atmosphere is 101325 Pa, approximately 1.01 × 10⁵ Pa.
56
Water depth in a dam is h, the wall's transverse area is A, and its thickness is t. Which combination determines hydrostatic pressure?
RRB SSE
21/12/2014 / Set-08, Green Paper
2014
✓ Answer:DNone of these
Pressure at depth h is ρgh, independent of wall area and thickness. None of the listed combinations states dependence on h alone for fixed fluid and gravity.
57
During melting of a pure crystalline solid at constant pressure, its temperature:
RRB Group-D
22/09/2018 / Shift II
2018
✓ Answer:DRemains unchanged
At the melting point, absorbed heat supplies latent heat for the phase change rather than raising temperature.
58
Mustard oil floats on water because:
RRB RPF Constable
07/03/2025 / Shift I
2025
✓ Answer:DOil is less dense than water
Mustard oil is immiscible with water and has lower density, so it forms the upper layer.
59
What is the approximate density of water?
RRB NTPC (Stage-I)
18/04/2016 / Shift II
2016
✓ Answer:A1000 kg/m³
Water's density is approximately 1000 kg/m³, with its precise value depending on temperature.
60
Which of the following is given as the reason clouds remain suspended in the sky?
RRB NTPC (Stage-I)
28/04/2016 / Shift II
2016
✓ Answer:DLow density
Source key: D. This is oversimplified: tiny droplets have low settling speeds because of air resistance, and rising air and turbulence help keep them suspended. Individual water droplets are denser than air.
