1)
Pressure can be exerted by
liquids only
solids only
solids, liquids and gases
solids and liquids only
2)
SI unit of pressure is
Pascal
Joule
Newton
Watt
3)
The pressure exerted by liquid
increases with depth
decreases with depth
is independent of the 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?
top
middle
distance covered does not depend on position of the hole
bottom
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
Water pressure is less in the tap downstairs.
The tap downstairs is smaller than the tap upstairs.
This case is not possible.
8)
Pressure of liquid depends on
shape of the container
none of these
size of the container
surface area of the container
