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.
