Q and S only
Correct answer is A
A system is in neutral equilibrium if its equilibrium is independent of displacements from its original position. A marble S on a flat horizontal surface is an example.
\(\gamma\)=a
\(\gamma\)=3\(\alpha\)
\(\gamma\)=2a
\(\gamma\)=\(\frac{1}{3} \alpha \)
Correct answer is B
cubic and linear expansivity are related by this equation. γ=3α.
0.5\(\pi\)

Correct answer is B
The period of a simple pendulum is doubled, when its length is made four times.
density
mass
weight
volume
Correct answer is C
Archimede's Principle states that a body immersed in a fluid experiences an upthrust equal to the weight of the fluid displaced, and this is fundamental to the equilibrium of a body floating in still water.
The area under a force-time graph represents--------
change in kinetic energy
change in momentum
change in work done
change in internal energy
Correct answer is B
It is a graph that represents the force that acts on a body in a certain amount of time.
Force on the object is represented by the y-axis and time taken by the object is represented by the y axis.
The area under the curve indicates the impulse, the change in momentum that the object undergoes.
