1)
Pressure can be exerted by
solids and liquids only
solids, liquids and gases
solids only
liquids only
2)
SI unit of pressure is
Pascal
Watt
Joule
Newton
3)
The pressure exerted by liquid
is independent of the depth
decreases with depth
increases with depth
will increase or decrease with depth depending on the density of the liquid
4)
The fluid pressure
more in downward direction
is very negligible in upward direction
is different in different direction depending on the shape of the container
is uniform in all direction
5)
What is lateral pressure?
The pressure exerted by a solid
The pressure exerted by the liquid in all directions combined.
The phenomenon where all points at the same level in a liquid are at the same pressure.
The pressure exerted by liquids on the walls of the container.
6)
The water stream coming out from hole located at which part of the bottle covers the maximum distance?
middle
bottom
distance covered does not depend on position of the hole
top
7)
Paheli found that the water in tap comes out faster downstairs than from a tap in her room upstairs even though the water is coming to taps from the same water tank on the terrace. What could be the possible reason for this observation?
The tap upstairs is at less depth than tap downstairs
This case is not possible.
The tap downstairs is smaller than the tap upstairs.
Water pressure is less in the tap downstairs.
8)
Pressure of liquid depends on
surface area of the container
size of the container
none of these
shape of the container
