A girl who wears heels with pointed soles will exert more pressure on the sand than a girl who wears heels with flat soles.
Because the pointes sole has less area than flat sole.Right?
So as we know ,
pressure=force/Area
Pressure is inversely proportional to the area.So the girl with point soles exert more pressure.
Thus by exerting pressure she pushes the sand inwards and she herself gets pushed downwards.
The girl with flat soles can walk comfortably because she exerts less pressure.
8) One student said water exerts pressure at bottom.The other said water exerts pressure on the walls of the container.
Both the students are correct.✓✓
Water exerts pressure in all directions.
And that pressure is same all through the container .
But an extra pressure is acting downwards due to the weight,(mg) of the water.
Pressure is exerted on all sides but it is more at the bottle.
8. Water exerts pressure from
all direction so. In this, both
boys are saying right.
