If a granite rock at the surface of the Earth has density 𝜌, what would be the density of the same rock on another planet with twice the acceleration of free fall compared to Earth?
2𝜌
In a closed U-shaped tube containing a stationary liquid of density 𝜌, what happens to the level of liquid when the tube is rotated about its axis?
The level remains unchanged.
If a ball is dropped from a certain height on Earth and on another planet where acceleration due to gravity is 30 m/s², how would the time taken for it to fall compare between the two planets?
It would take the same time on both planets.
In the scenario described, what allows the child and the sledge to move with equal acceleration towards the pole?
The tension in the rope exerted by the child
What is the significant similarity between the stone S and foam rubber ball R when they reach terminal velocity?
Their air resistance
If the collision between balls X and Y was not perfectly elastic, what would be a possible outcome for ball X after the collision?
Ball X comes to a complete stop
What role does the frictionless pole play in the scenario involving the child and the sledge?
To provide a pivot point for rotational motion
What key property of balls X and Y determines their interaction during a head-on collision?
Their elasticity
How does the concept of terminal velocity relate to the scenario involving stone S and foam rubber ball R?
Terminal velocity is achieved when air resistance equals weight for an object
