The ability of a material to deform without breaking is called:
RRB JE
14/12/2014 / Set-2, Red Paper
2014
✓ Answer:CPlasticity
The intended answer is plasticity: the ability to undergo permanent deformation without fracture. Elasticity instead involves recovering the original shape.
92
For a perfectly elastic collision, the coefficient of restitution is:
RRB JE
14/12/2014 / Red Paper
2014
✓ Answer:C1.0
The relative speed of separation equals the relative speed of approach, so e = 1.
93
Which property makes small falling water drops approximately spherical?
RRB JE
14/12/2014 / Set-2, Red Paper
2014
✓ Answer:ASurface tension
Surface tension minimizes surface area; a sphere has the least area for a given volume. Large falling drops can be distorted by airflow.
94
Buoyant force depends on the density and _____ of the liquid displaced.
RRB JE
31/05/2019 / Shift III
2019
✓ Answer:BVolume
Buoyant force is ρgV, where V is the displaced liquid volume.
95
Bernoulli's theorem is based on conservation of:
RRB JE
30/08/2019 / Shift I
2019
✓ Answer:DEnergy
For steady ideal flow along a streamline, pressure, kinetic and gravitational energy per unit volume have a constant sum.
96
The centre of buoyancy always:
RRB JE
14/12/2014 / Yellow Paper
2014
✓ Answer:BCoincides with the centroid of the displaced fluid volume
For a uniform-density fluid, buoyancy acts through the centroid of the displaced volume.
97
At what temperature is the density of water maximum?
RRB JE
14/12/2014 / Red Paper
2014
✓ Answer:D4°C
At ordinary pressure, pure water has its maximum density at approximately 4°C.
98
In which state is intermolecular attraction generally strongest?
RRB JE
14/12/2014 / Green Paper
2014
✓ Answer:ASolid
In solids, particles are closely bound and vibrate about relatively fixed positions.
99
Gas molecules exert force on a vessel's wall because of:
RRB JE
14/12/2014 / Red Paper
2014
✓ Answer:DChanges in momentum during collisions with the wall
The wall changes molecular momentum during collisions. The rate of momentum transfer produces force and pressure.
